Make A= width of envelope, B= height of envelope, X= width of paper, Y= height of paper.

Find lowest possible positive integers l,m and n,o so that X/l < A, Y/m < B, X/n < B, Y/o < A

compare l+m and n+o, and pick the lowest of the two. If equal, prefer powers of two, even numbers, odd numbers in that order. Of the chosen pair, the first number (l or n) is the amount of folds over the paper's width, and the second (m or o) the amount of folds over its height.
