This depends on what the behavior is of the division operator. People should use floor division, then implementing modulo is easy.

I don’t know what is available as chip instructions, I could certainly believe hardware designers made the wrong choice.

I take the opinion that people should have the option to round division (and compute remainders) however they want: down, up, to zero, to nearest (with different options for breaking ties).

Common Lisp has all four division operators ('floor', 'ceiling', 'truncate' (equivalent to what most languages consider division), and 'round') [0], and both 'mod' and 'rem' [1].
