Abstract
A division apparatus. A quotient of one digit and a remainder are determined by repeating execution of a single type processing of adding an integral multiple of a divisor and an intermediate remainder. The apparatus includes first, second and third registers for storing a dividend or the intermediate remainder, the integral multiple of a divisor and a carry resulted from a preceding operation, respectively, a selection circuit for selecting the complement of the integral multiple of the divisor when the carry is zero while selecting the integral multiple of the divisor when the carry is 0, an arithmetic circuit for performing adding operation on the output of the selection circuit and the content of the first register with the carry being served as the initial carry, and a counter for counting a number which corresponds to the integral multiple of the divisor. The result of the arithmetic operation which is executed in dependence on the value assumed by the carry is placed in the first register. The quotient is determined on the basis of the content of the counter.
