An integrated circuit comprises divider circuitry configured to perform a division operation. The divider circuitry may be part of an arithmetic logic unit or other computational unit of a microprocessor, digital signal processor, or other type of processor. The divider circuitry iteratively determines bits of a quotient over multiple stages of computation. In determining the quotient in one embodiment, the divider circuitry is configured to estimate a partial remainder for a given one of the stages and to predict one or more of the quotient bits for one or more subsequent stages based on the estimated partial remainder so as to allow one or more computations to be skipped for said one or more subsequent stages, thereby reducing power consumption. The integrated circuit may be incorporated in a computer, a mobile telephone, a storage device or other type of processing device.
