Explanation
 The binary floating-point value in S
1
is divided by the binary floating-point value
in S
2
, and the quotient is stored in D.
 S
1
: Dividend; S
2
: Divisor; D: Quotient and remainder
 If S
1
is a floating-point value, the instruction will be used to divide S
1
by the
binary floating-point value in S
2
. If S
2
is a floating-point value, the instruction
will be used to divide the binary floating-point value in S
1
by S
2
.
 If the value in S
2
is 0, an operation error will occur, the instruciton will not be
executed, an operation error flag will be ON, and the error code H0E19 will
appear.
 If the absolute value of an oepration result is greater than the maximum
floating-point value available, a carry flag will be ON.
 If the absolute value of an oepration reuslt is less than the minimum
floating-point value available, a borrow flag will be ON.
 If an operation result is 0, a zero flag will be ON.
Example 1

When X1 is ON, the binary floating-point value in (D1, D0) is divided by the
binary floating-point value in (D11, D10), and the quotient is stored in (D21,
D20).

Example 2

When X2 is ON, the binary floating-point value in (D1, D0) is divided by
F1234.0, and the quotient is stored in (D11, D10).
