Mnemonic
DIV DIVIDE INTEGERS. Divides the contents of
the destination long-integer operand by the
contents of the source integer word operand,
using signed arithmetic. It stores the quotient
into the low-order word of the destination
(i.e., the word with the lower address) and the
remainder into the high-order word. The
following two statements are performed
concurrently.
(low word DEST)
(high word DEST)

DIVB DIVIDE SHORT-INTEGERS. Divides the
contents of the destination integer operand
by the contents of the source short-integer
operand, using signed arithmetic. It stores the
quotient into the low-order byte of the
destination (i.e., the word with the lower
address) and the remainder into the high-
order byte. The following two statements are
performed concurrently.
(low byte DEST)
(high byte DEST)
Z

DIVU DIVIDE WORDS, UNSIGNED. Divides the
contents of the destination double-word
operand by the contents of the source word
operand, using unsigned arithmetic. It stores
the quotient into the low-order word (i.e., the
word with the lower address) of the
destination operand and the remainder into
the high-order word. The following two
statements are performed concurrently.
(low word DEST)
(high word DEST)
