Function num_bigint_dig::algorithms::div_wide

pub fn div_wide(hi: u64, lo: u64, divisor: u64) -> (u64, u64)

Divide a two digit numerator by a one digit divisor, returns quotient and remainder:

Note: the caller must ensure that both the quotient and remainder will fit into a single digit. This is not true for an arbitrary numerator/denominator.

(This function also matches what the x86 divide instruction does).
