a/b = c has meaning only if c is uniquely determinable. If there are
lots of candidates for c, then the "division" of a by b is not well
defined.

The general definition of such a quotient, c in a/b = c, is the unique
solution for c to the equation a = b c.

But every number, c, is a solution to 0 = 0 c, so the uniqueness
requirement fails.
