what is the equation to divide any numerical value by zero

In algebraic terms, the division by zero is
meaningless.

You can think in this way: what expression
multiplied by zero gives other value than zero? The answer is simple,
none.

for instance, we'll consider a polynomial of n-th
order:

P(x) = `a_(1)` *`x^(n)` + `a_(2)` *`x^(n-1)` + ... +
`a_(0)`

We'll divide this polynomial by
0:

P(x)/0 = ? => 0*? =
P(x)

Unless P(x) reprezents zero polynomial, no other value
multiplied by zero gives such a value that is different from
zero.
