DIV - Divide

	Usage:	DIV	src
	Modifies flags: (AF,CF,OF,PF,SF,ZF undefined)

	Unsigned binary division of accumulator by source.  If the source
	divisor is a byte value then AX is divided by "src" and the quotient
	is placed in AL and the remainder in AH.  If source operand is a word
	value, then DX:AX is divided by "src" and the quotient is stored in AX
	and the remainder in DX.
