Integer Division (unsigned) With Remainder
The following algorithm, the binary version of the famous long division, will divide N by D, placing the quotient in Q and the remainder in R. All values are treated as unsigned integers.]]
if D == 0 then throw DivisionByZeroException end
Q := 0 initialize quotient and remainder to zero
R := 0
for i = n-1...0 do " where n is number of bits " R := R << 1 left-shift R by 1 bit R(0) := N(i) set the least-significant bit of R equal to bit i of the numerator if R >= D then R = R - D Q(i) := 1 end
end

Famous quotes containing the words division and/or remainder:
“Major [William] McKinley visited me. He is on a stumping tour.... I criticized the bloody-shirt course of the canvass. It seems to me to be bad “politics,” and of no use.... It is a stale issue. An increasing number of people are interested in good relations with the South.... Two ways are open to succeed in the South: 1. A division of the white voters. 2. Education of the ignorant. Bloody-shirt utterances prevent division.”
—Rutherford Birchard Hayes (1822–1893)
“Do not undervalue the headache. While it is at its sharpest it seems a bad investment; but when relief begins, the unexpired remainder is worth $4 a minute.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
