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:
“Imperialism is capitalism at that stage of development at which the dominance of monopolies and finance capitalism is established; in which the export of capital has acquired pronounced importance; in which the division of the world among the international trusts has begun, in which the division of all territories of the globe among the biggest capitalist powers has been completed.”
—Vladimir Ilyich Lenin (1870–1924)
“The route through childhood is shaped by many forces, and it differs for each of us. Our biological inheritance, the temperament with which we are born, the care we receive, our family relationships, the place where we grow up, the schools we attend, the culture in which we participate, and the historical period in which we live—all these affect the paths we take through childhood and condition the remainder of our lives.”
—Robert H. Wozniak (20th century)
