quotient’s overflow and zero division by software before DIV instruction is
executed. This instruction changes the Stack Pointer and the contents of the
Accumulator.

M(S) ← one’s complement of Remainder
(S) ← (S) – 1
Divides the 16-bit data in M(zz+(X)) (low-order byte) and
M(zz+(X)+1) (high-order byte) by the contents of A. The
quotient is stored in A and the one’s complement of the
remainder is pushed onto the stack.
