	The source operand can be a general-purpose register or a memory location. The action of this instruction depends on the operand size (dividend/divisor). Non-integral results are truncated (chopped) towards 0. The remainder is always less than the divisor in magnitude. Overflow is indicated with the '''#DE''' (divide error) exception rather than with the '''CF''' flag.		The source operand can be a general-purpose register or a memory location.
