Divide each element in a column by the sum of that column

I have a 2x10 matrix called A. I would like to find the sum of each column in A and divide individual elements in A by the sum for each column.
ex. A = [12 45 67 23 45 43 23 23 23 56
23 45 65 32 45 67 32 45 88 76];
B = sum(A) i.e [ 35 90 132 55 90 110 55 68 111 132];
Next, I want to divde 12 & 23 by 35, 45 and 45 by 90 and so on. How do I do this?

Specify the dimension argument to avoid bugs if the matrix happens to contain just one column:
A = [12,45,67,23,45,43,23,23,23,56;23,45,65,32,45,67,32,45,88,76];
B = A./sum(A,1)
