When CIO 000000 is ON in the following example, the contents of CIO 0013
and D00005 are multiplied and the results is placed in CIO 1207 and CIO 1208.
Example data and calculations are shown below the program.

When the execution condition is OFF, DIV(073) is not executed and the program
moves to the next instruction. When the execution condition is ON, Dd is divided
by Dr and the result is placed in R and R + 1: the quotient in R and the remainder
in R + 1.

Note With version-2 CVM1 CPUs, mathematics instructions can use symbols. The
instructions corresponding to DIV(073) and DIVL(077) are /B(434) and /
BL(435).
Dd and Dr must be BCD.
Note Refer to page 115 for general precautions on operand data areas.
Flags ER (A50003): Content of Dd or Dr is not BCD.
Content of *DM word is not BCD when set for BCD.
EQ (A50006): The result is 0.
