Where did this next quote come from? I have not seen any recent posts by 
Kevin Darling. In any case, the following quote is incorrect!

Actually if the division would result in overflow, nothing happens. If 
the division works, the quotient is stored in regB with the remainder in 
regA. Try the following tests and see:

start	ldd	#4326
	divd	#2
	swi
	end

start	ldd	#432
	divd	#2
	swi
	end

start	ldd	#433
	divd	#2
	swi
	end

These can be compiled in EDTASM, run in DEBUG, and the registers 
examined. At least you can do it if you have my EDTASM6309. The content 
of regD will be $10E6, $00D8, and $01D8 respectively.
