How to sort files into subfolders based on identical names?

I have a folder full of files labelled as follows:

76.png
77.png
78.png
79.png
...

I also have a folder that contains subfolders named identical to above, i.e.:

76
77
78
79
...

I would like to use a batch file to sort each of these files into the respective subfolders quickly. Is there any way to do this? Thanks in advance!
