LDA	5001H	; Load Acc with content of 5001 H
	MOV B, A	; Move Acc to Reg. В
	LDA 5000H	; Load Acc with content of 5000H
	MVI C, OOH	; Inhalize Reg. C to OOH
BACK:	SUB B	; Subtract B from Acc
	JC-SKIP	; If carry go to SKIP
	INR C	; Increment Reg. C by 1
	JMP-BACK	; JUMP to Back
SKIP	ADD B	; Add Reg. B to Acc
	STA 5003 H	; Store remainder at 5003Н
	MOV A, C	; Move Reg. B to Acc
	STA 5002 H	; Store quotient at 5002 Н
