Divide different planar surfaces in to equall sized panels

So, here's a few images of what I have and what I'd like to have. 

I know I can't get the panels to fit perfectly because the lengths of all surfaces isn't the same, which would only be possible if the walls lengths were: example. in increments of 3 ft,4 ft, or 5 ft etc., but it'd be nice if I could split the extra space that doesn't make a full panel on to edges. 

Help is much appreciated!

Also, I am a beginner with grasshopper.
