Notes on operand usage:
The 16-bit command operand D will occupy 2 consecutive points

S1
: Dividend.
S2
: Divisor.
D
: Quotient and remainder.
 Using two data sources: The quotient and remainder will be stored in
D
when
S1
and
S2
are subjected to division using the BIN method. The sign bit for
S1
,
S2
and
D
must be kept in mind when performing a 16-bit operation.
16-bit BIN division:
+1
= /
Quotient
Remainder
If
D
is a bit device, K1-K4 can be designated 16 bits, which will occupy 2
consecutive units and yield the quotient and remainder.
 When X0=On, the quotient resulting from division of dividend D0 by divisor D10
will be placed in D20, and the remainder will be placed in D21. Whether the
highest bit is Off or On will indicate the sign of the result.
