Function
z Divides s1 by s2 as signed binary data, and substitutes the quotient into d in signed binary data. The remainder is set in the
special internal output DRF016 signed binary data.
z The DER flag is 1 if s2 is 0, and the operation is not performed. As long as s2 is not 0, it is 0 and the operation is
performed.
z The V flag is 1 when the quotient is a positive value and exceeds H7FFFFFFF. Otherwise, it is 0.

Program description
z
When input X00000 turns on, the value of DR0056 is divided by the value in DR0058, then substituted into DR0060 as
signed binary data. The remainder is substituted into special internal output DRF016 as signed binary data.
