   Quote from the MC88100 Risc Microprocessor User's Manual:

	page 3-48, description of the FDIV instruction.

	Description:  The contents of the rS1 and rS2 registers [any g.p. source
		register] are checked for reserved operands.  If no reserved operands
	 	are found, the rS1 operand is divided by the rS2 operand according
		to the IEEE 754.  The result is placed in the rD register.  Any
		combination of single- and double-precision operands can be specified.

  Obviously, the 88K DOES do divide.  There are also instructions for signed and unsigned
integer divide.
