Division (digital)
A division algorithm is an algorithm which, given two integers N and D, computes their quotient and/or remainder, the result of division. Some are applied by hand, while others are employed by digital circuit designs and software.
Division algorithms fall into two main categories: slow division and fast division. Slow division algorithms produce one digit of the final quotient per iteration. Examples of slow division include restoring, non-performing restoring, non-restoring, and SRT division. Fast division methods start with a close approximation to the final quotient and produce twice as many digits of the final quotient on each iteration. Newton-Raphson and Goldschmidt fall into this category.
Discussion will refer to the form where
- Q = Quotient
- N = Numerator (dividend)
- D = Denominator (divisor).

Famous quotes containing the word division:
“Dont order any black things. Rejoice in his memory; and be radiant: leave grief to the children. Wear violet and purple.... Be patient with the poor people who will snivel: they dont know; and they think they will live for ever, which makes death a division instead of a bond.”
—George Bernard Shaw (18561950)
