    Hey guy, try this...
    Code:
               LHLD 2200H   ; Get the devidend
               LDA 2202H
               MOV C, A      ; Get the divisor
               LXI D, 0000H ; Quotient = 0
    BACK : MOV A, L
               SUB C           ; Subtract divisor
               MOV L, A       ; Save partial result
               JNC SKIP        ; if CY # 1 jump
               DCR H            ; Subtract borrow of previous subtraction
    SKIP :  INX D             ; Increment quotient
               MOV A, H
               CPI, 00          ; Check if dividend < divisor
               JNZ BACK       ; if no repeat
               MOV A, L
               CMP C
               JNC BACK
               SHLD 2302H   ; Store the remainder
               XCHG
               SHLD 2300H   ; Store the quotient
               HLT
