A higher-radix type divider is provided which is capable of obtaining a quotient at a high speed by performing a scaling on a divisor and by representing a partial remainder in a redundant binary notation.
The divider for obtaining the quotient by referring to the divisor and dividend normalized respectively so as to satisfy a range of ½K or more and less an ½K+1 (k being a positive integer) and to a length of bits, out of all bits of the partial remainder, defined by a radix for operations and a maximum number of digits, is provided with a scaling factor generating section, a multiplying section, a divisor tripled-number generating section and a repetitive operating section.
