Performs Euclidean division.
Since, for the positive integers, all common definitions of division are equal,
this is exactly equal to `self / rhs`.
# Panics
This function will panic if `rhs` is zero.
# Examples
Basic usage:
```
# use ::exint::primitive::*;
# ::exint::uint! {
assert_eq!(7_u24.div_euclid(4_u24), 1_u24);
# }
```
