Description /B(434) divides the BCD content of Dd by those of Dr and outputs the quotient
to R and the remainder to R+1.
Flags
Precautions If Dd or Dr are not BCD or if the remainder (R+1) is 0, an error will be gener-
ated and the Error Flag will turn ON.
If as a result of the division, the content of R is 0000 hex, the Equals Flag will
turn ON.
If as a result of the division, the leftmost bit of R is 1, the Negative Flag will
turn ON.
