When the execution condition is OFF, DIV(33) is not executed and the next
instruction is moved to. When the execution condition is ON, the content of
Dd is divided by the content of Dr and the result is placed in R and R + 1: the
quotient in R and the remainder in R + 1.

ER: Dd or Dr is not in BCD.
Indirectly addressed DM word is non-existent. (Content of *DM word
is not BCD, or the DM area boundary has been exceeded.)
EQ: ON when the result is 0.
When IR 0000 is ON with the following program, the content of IR 20 is di-
vided by the content of HR 9 and the result is placed in DM 17 and DM 18.
Example data and calculations are shown below the program.
