DIVIDE returns the quotient of x/y with a precision specified
by p and q. The base, scale, and mode of the result
follow the rules for expression evaluation unless overruled by the
PRECTYPE compiler option.

- x
- Expression.
- y
- Expression. If y = 0, the ZERODIVIDE condition is raised.
- p
- Restricted expression specifying the number of digits to be maintained throughout the operation.
- q
- Restricted expression specifying the scaling factor of the result. For a fixed-point result, if q is omitted, a scaling factor of zero is the default. For a floating-point result, q must be omitted.
