Division is still optional in ARM; their smallest core (Cortex-M0) does not have it. That makes perfect sense for that class of embedded core; to be honest, div

Division is still optional in ARM; their smallest core (Cortex-M0) does not have it. That makes perfect sense for that class of embedded core; to be honest, division by a variable is a very rare operation in embedded code (division by a constant is multiplication by the reciprocal, so that doesn't need a division instruction).
