Notes on operand usage:
Refer to the function specifications table for each device in series
for the scope of device usage.
 S
1
: dividend. S
2
: divisor. D: quotient.
 Divides the content of the register designated by S
1
by the content of the
register designated by S
2
and stores the quotient in the register designated by
D; division is performed entirely using binary floating point numbers.
 If the source operand S
1
or S
2
designates a constant K or H, the command
converts that constant into a binary floating point number for use in division.
 When X1 = ON, divides the binary floating point number (D1, D0) by the binary
floating point number (D11, D10), and stores the quotient in the register
designated by (D21, D20).

 When X2 = ON, divides the binary floating point number (D1, D0) by K1,234
(which is automatically converted to a binary floating point number), and stores
the results in (D11, D10).
