[0.17.79] Allow "each" as divisor of division operator

[JasonC]

Correct me if I'm wrong but it does not appear possible to use "each" as the divisor (right hand side) of the division operator in arithmetic combinators (e.g. "each = constant / each" or "each = signal / each").

I would like this to be possible, either by allowing "each" to be used on the right hand side (the most flexible and tidy option) or by adding some sort of "inverse division" operator that divides the right side by the left so "each" on the left can be used as the divisor (a similar "inverse modulo" should probably be added for completeness here, then).
