32-bit Variables and DIV32, Hourmeter 99999.9
http://www.picbasic.co.uk/forum/showthread.php?t=1942

Should work, but I haven't tested the modification.
Code:
BigVar    VAR WORD[2]    ; 32-bit (Dword)
  Var1    VAR BigVar(1)
  Var2    Var BigVar(0)

Result    Var Word
Remainder Var Word

;----[Load a 32-bit (Dword) variable into PBP registers, Prior to DIV32]-----
Asm
PutMulResult?D macro Din
    MOVE?BB   Din, R2
    MOVE?BB   Din + 1 , R2 + 1
    MOVE?BB   Din + 2, R0
    MOVE?BB   Din + 3, R0 + 1
    RST?RP
  endm
EndAsm

;====[Simple loop to test Big Numbers]=======================================
Start:
    Var1 = 1
    Var2 = %1111101111010000

MainLoop:
    LCDOUT $FE,1        ; clear screen
    Gosub ShowBigNumber
    PAUSE 1000
    Var2 = Var2 + 1
    if Var2 = 0 then Var1 = Var1 + 1
goto MainLoop    
;===========================================================


;----[Display 32-bit value with 2 decimals using LCDOUT]---------------------
ShowBigNumber:
@   PutMulResult?D  _BigVar
    Result = DIV32 1000
    Remainder = R2
    LCDOUT $FE, 2            ; Home Cursor
    IF Result > 0 then
        LCDOUT Dec Result, DEC1 Remainder/100,".",DEC2 Remainder//100
    else
        LCDOUT DEC Remainder/100,".",DEC2 Remainder//100
    endif   
return
