My question is: Is there a way to force 0/0 and x/0 to result in 0?
Thank you,

I don't know of a way. You may want to try first running a loop
replacing 0 with inf throughout the denominator array. Then run
vectorized division; any non-inf divided by inf yields 0.

I would not recommend this unless you use the denominator array to
divide several other arrays.
A single pass will be faster and more clear, I think.
