If you just want to split each file into files of a fixed number of lines or bytes, you can use the split command.
I found this. You may need to find the number of parts to be splited it too first.
You can use csplit, which can split by context. Check the man/info page of csplit for more info.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
