Divide (DIV)
Divide is a 16-bit instruction that divides the BCD value in
230
the accumulator by a BCD value (Aaaa), which is either a
240
V-memory location or a 4-digit (max.) constant. The first
250-1
part of the quotient resides in the accumulator and the
remainder resides in the first stack location.

NOTE: The status flags are only valid until another instruction that uses the same flags is executed.
In the following example, when X1 is on, the value in V2000 will be loaded into the
accumulator using the Load instruction. The value in the accumulator will be divided by the
value in V2006 using the Divide instruction. The value in the accumulator is copied to
V2010 using the Out instruction.

On when the value of the operand is larger than the accumulator can work with.
On when the result of the instruction causes the value in the accumulator to be zero.
On anytime the value in the accumulator is negative.
On when a BCD instruction is executed and a NON-BCD number was encountered.
