0/0

Executive Summary

You said something that does not compute, and I'm done with trying to explain it.

Explanation

What you said is fundamentally illogical. It somehow fails to take into account the evidence presented, or else proceeds from that evidence to draw a nonsensical conclusion. Furthermore, you have made this type of error many times before, and have ignored (or at least obviously not understood) my explanations of the problem.

Mathematics

Zero cannot be divided by zero; depending on the calculation method used, the answer to "zero divided by zero" (0 / 0)) can either be literally anything or else result in an infinite loop (the calculation never completes). Pocket calculators, calculator apps, and computer CPUs will return an error when this (or any other divide-by-zero) operation is attempted.

In algebra, it may be possible to get a meaningful answer by factoring out terms which are resulting in a multiply-by-zero on both sides of the equation.

Some functions which result in a 0/0 at a certain point can be worked out through calculus, using limits.
