If I recall the MPASM thingo has some problems, and often truncated to
16bits for equates. If this problem does not exist, then you should be able
to do things like

dividendo
(dividendo+1)
(dividendo+2)
(dividendo+3)

Note that there is no range checking as it sees all as the one location
(Could use high and low for 16 bits). And I am assuming that it makes this
a 32 bit number. But I am not sure at all.
