 If a word device has been used, the result of the division operation is stored as 32 bits, and both the quotient and remainder
are stored.
Quotient: Stored at the lower 16 bits
Remainder: Stored at the higher 16 bits
 The values for (S1) and (S2) can be designated between -32768 and 32767 (BIN 16 bits).
 Judgments whether (S1),(S2), and (D) are positive or negative are made on the basis of the most significant bit (b15 for
(S1) and (S2), and b31 for (D)).
b15/b31 Judgment (+/-)
0 Positive
1 Negative
 When divisor S2 is "0", no operation is carried out.
 Operation errors
 There are no arithmetic errors associated with the "*", "*P", "/", or "/P" instructions.
