Here.  This routine separates the number into three digits; if you 
know your original number won't ever be larger than 99 decimal, you 
can remove all the lines marked with a "*****" comment and it'll just 
separate the number into two digits:

     LIST    R=DEC

     UNITS    EQU     ....    ;A FILE REGISTER.
     TENS     EQU     ....    ;ANOTHER FILE REGISTER.
     HUNDREDS EQU     ....    ;ANOTHER FILE REGISTER.  *****

; ENTER WITH ORIGINAL 8-BIT VALUE IN "UNITS".  EXITS WITH ONES'
; DIGIT IN "UNITS", TENS' DIGIT IN "TENS", AND HUNDREDS' DIGIT
; IN "HUNDREDS".

  CONVERT CLRF    TENS
          CLRF    HUNDREDS    ; *****

  DO100S  MOVLW   100         ; *****
          SUBWF   UNITS,W     ; *****
          BNC     DO10S       ; *****

          MOVWF   UNITS       ; *****
          INCF    HUNDREDS    ; *****
          GOTO    DO100S      ; *****

  DO10S   MOVLW   10
          SUBWF   UNITS,W
          BNC     ADJUST

          MOVWF   UNITS
          INCF    TENS
          GOTO    DO10S

  DONE
