The DEC Alpha line of processors famously lack integer division:

> There is no instruction(s) for division as the architects considered the implementation of division in hardware to be adverse to simplicity.

Interestingly, ARM11 used in original RPi and RPi Zero also doesn't have integer division, but it has floating point division.

Divide being missing is not totally uncommon in CPU architecture. If I'm not mistaken, the Cray-1 didn't have a divide instruction either, just reciprocal approximation.

SH4 (and SH2 I think?) was an interesting mid point, which architecturally exposed the single cycle ops that would back an iterative divide, letting you pick the precision you wanted.
