Assume the problem is:
91%2F%28m%5E2-169%29
-----------
7%2F%282%28m%2B13%29%29
:
Invert the dividing fraction and multiply
91%2F%28m%5E2-169%29 * %282%28m%2B13%29%29%2F7
Factor the 1st denominator, the difference of squares
91%2F%28%28m-13%29%28m%2B13%29%29 * %282%28m%2B13%29%29%2F7
Cancel 7 into 91 and the (m+13)'s
%2813%2A2%29%2F%28m-13%29 = 26%2F%28m-13%29
