Matrix Division: Getting all 1s for my end result

Hey guys,
I am trying to do a matrix division by using the A./B function for a 2 large identical sized matrix. However, the end result is a same sized matrix with all 1s, despite both matrix A and matrix A having different values.
I tried creating a 2 small matrix to try out the division, and it works. But it doesn't work for my actual matrix.
Can anyone tell me what is going on?
Regards
Guan Zhao

See my answer below. You need to convert A and B to floating point type (they are currently integer type uint8) in order to do floating point math with them.

See if this makes a difference
double(A)./double(B)
