Explanation of example
Divides the contents of data register DT10 by decimal constant DT20 when trigger R0 turns on. The quotient
is stored in data register DT30 and the remainder is stored in special data register DT9015/DT90015.
When the decimal number 15 is in DT10 and the decimal number 4 is in DT20, as shown below.
