8051 Program - unsigned 8bit division

; subroutine UDIV8

; 8-Bit / 8-Bit to 8-Bit Quotient & Remainder Unsigned Divide

;

; input: r0 = Dividend X

; r1 = Divisor Y

;

; output: r0 = quotient Q of division Q = X / Y

; r1 = remainder

;

; alters: acc, C

UDIV8:	push b
	mov a, r0	;read X and ...
	mov b, r1	;... Y
	div ab	;divide X and Y
	mov r0, a	;save result quotient
	mov r1, b	;save remainder
	pop b
	ret
