divideCoefficientBy()

inlineconstexpr

We do not provide the '/' operator here because division for polynomial types does not work in the same way as for normal integer types.

We can only divide the minimum value (or coefficient) by RHS, which is not the same as (Min * Vscale) / RHS The caller is recommended to use this function in combination with isKnownMultipleOf(RHS), which lets the caller know if it's possible to perform a lossless divide by RHS.
