60 | first, we divide the divisor and dividend by two until 
69 | now we can do the divide.  to avoid overflow, we have to 
70 | do the divide in two parts, high and low, and add the 
75 	divuw	%d0, %d1	| do the high divide
76 	moveal	%d1, %a1	| save high divide result
78 	divuw	%d0, %d1	| do the low divide
79 	movel	%a1, %d0	| recover high divide result
81 	clrw	%d0		| %d0 = finished high divide result
82 	andil	#0xffff, %d1	| %d1 = finished low divide result
85 | the quotient we have so far is only a guess.  the divide we 
86 | did above was really the divide of some dividendB by some
