Just posting this here for record purposes.

This code will break down a decimal value to individual digits by getting its base, e.g. 125 (decimal value) to 1, 2, and 5.

valin    equ 0x1C
hundreds equ 0x1D
hpasses  equ 0x1E
tpasses  equ 0x1F
tens     equ 0x0C
ones     equ 0x20

start     movlw 0x1F  ;example value coming from lm35 to
        movwf valin      ;adc0804 and finally to 16f84
        movf  valin,w
        movwf hundreds

mainhundreds movlw 0x64             
  subwf hundreds
  btfsc STATUS, C
  goto  counthundred
        movlw 0x64
        addwf hundreds

        movwf tens

        subwf tens
