Selecting a block of values in a matrix.

I am currently working on a problem where were are given a matrix that can vary in size. Then we must select a block (5x5) of that matrix starting from the top left corner and replace all the values with the average of those values. After that this process is repeated for the entirety of the matrix. I believe I can do the code to find the average and replace the values, but I do not know were to start to select the blocks of the matrix. I know that I need to use nested for loops but so far I have not been able to get it.
Thanks in advance :)
