Not quite sure what you're getting at, but no, you can't get a returned value of 0 when the denominator is 0, because division by 0 is undefined.

Reasons's easy....

if n/d = r (r for result)

then n=d * r

if d=0

then n=0 * r

no value of r, even infinity, will bring you the original n, because 0 * r = 0 for all r
