Hi laurence,
in order to exactly follow the movement of the planets or points you need to use a programme or look in the ephemeris. Ephemeris are the tables showing the exact positions for each day, for each planet or point. It is not that hard to use them.
You can find the ephemirs here:
http://www.astro.com/swisseph/swepha_e.htm
You look in 21st century, year 2017 (you don't need to look at those tables that say 'with declination and latitude', just look into the basic ones). If you click on 2017, the whole year opens, you search for May. If you take a look at 10th May, you will see that the north node is marked as entering Leo (29 degrees). Sometimes the date or hour can vary, depending on whether the ephemerisis are set for noon or midnight, which part of the world is taken in question, etc, but this doesn't have that much significance for your use.
You need to know the symbol for the north node - or for any planet or point that you want to look at. If you don't know the symbol, just type it into google, you will find it very quickly. And then you can just search for it in the ephemeris.
With nodes, there are two possibilities - you can use the True Node or the Mean Node. You can read more about it on internet, I won't go into lengthy talk now, it has to do whether you chose the 'true position', or the average position of the movement. The difference is extremely small, almost neglectable, so it is just a matter of choice which position to use. In this ephemeris, both positions are given, true and mean: mean is the third from the back, and the true position is the fourth from the back. If you know the symbol for the node, you will see that the true position is marked with a small 't' inside.
You can choose whichever position you like; there is a small difference, as you will see, the mean node entered leo on 29th of April, whereas the true node on 10th of May - and with the true node you also notice this small retrograde-direct movement. It has to do with astronomy, you can read more about it and the nodes in general here:

So as for the ephemeris: for each planet/point the changes in degrees are marked as the planet moves on a daily basis. This way you can follow the movements through the ephemeris. For instance, if you take a look at the 1st may, you will see that the north node (true) is at 0 degree of Virgo - and then you see an R written next to it. This means that its movement is retrograde. Then there is a small window of direct motion - and you will see this marked with D. And then again R and again D in the next few days. This is the 'wobbling' of the true node, it goes back and forth - in the mean node this wobbling is taken out and only the average position is calculated.
Anyways, this doesn't matter so much, whether you chose to follow the 'wobbling' or not - the point is to see the changes in the signs. It is true that the mean node entered Leo a little earlier, but in overall, these are small differences.
So this is the first part, know how to look at the ephemeris. You can also have astrological programs that draw how the planets move, but if you don't have such a programe, you simply look at the ephemeris. It is very easy to read them, nothing complicated, you have all the degrees shown for each planet on a daily basis, if you see an R, this menas that the planet changed its movement into retrograde motion, and if you see a D, this means that the planet moves direct again. This is basically all you need to pay attention to. Remember that Sun and Moon are never retrograde, so you won't find and R or D with them.
Now you need to look at your natal chart - you need to see at which degrees of the zodiac signs your houses begin and end. Your second house begins at 21 degrees of Leo (the image your provided does not show minutes, so we can only discern degrees, but this is perfectly fine and sufficient), and ends at 13 of Virgo. Can you see that in your chart? Do you know what the ascendant is, which line? It is the very first line on the left side of the circle, it is usually marked bold since ascendant-descendant axis has a great importance. Your ascendant is at 3 degrees of Leo - do you see that? Just look for the symbol of leo and you will recognize it in your chart. The ascendant is at the same time - in the system we use (there are other options) - the cusp of your first house. So this means, your ascendant is at 3 degrees of Leo AND your first house begins at 3 degrees of leo. Then you have to follow and see the cusp of your second house which is at 21 degrees of Leo. And then the next house, the second, begins at 13 degrees of Virgo - and this is also the end of the second house, of course. And then the fourth house begins at 13 degrees of Libra, etc. Can you follow this? if you do, then it is very easy - just see in the ephemeris where the planet or point you want to look at is on the day you are interested in. So North node is NOW, 11th of May, at 29 degrees 44 minutes of leo (true position). So now you go and search this exact degree of leo (29-44) in your chart - and you will find it in your second house. This means that the TRANSITING north node is now in your second house.
You can trace all the planets/points in this way. You do need to know the zodiac symbols, see the cusps of the houses - but this is basically just like reading a circle. The whole circle has 360 degrees, each sign takes 30 degrees. In this system that we use, the houses begin somewhere inside of the sign. You just need to see the cusp and you can discern your houses.
Is this clear? it is not so easy to write it all down, but it is basically very simple. Of course the interpretation and understanding of what the movements mean and how they reflect in our lives, that is another story
But just to see where the transiting planets or points are in our charts, you basically just need to trace the movements in the ephemeris and then place them in your circle, your natal chart, looking for the exact same degree of the sign.
