Splitting data with different matrix sizes

I have a flexible data which gets increased in size. for instance: A1=1:200 A2=1:240 A3=1:270 I am looking for a way to split my data into (for instance 8 different sections) in each time (A1, A2 and A3) . The last section would be smaller/ larger but the first 7 sections should be constant in size.

So we would have 8 different sections at A1, 8 different sections at A2, 8 different sections at A3.
