Abstract
A dividing apparatus which allows settlement of a quotient of one digit with a simple circuit construction is disclosed. A plurality of different integer multiples are simultaneously subtracted individually from a dividend or an intermediate remainder, and when all of results of the subtraction are in the negative in sign, the dividend or intermediate remainder before the subtraction is selected as it is as a new intermediate remainder, but when some or all of the results of the subtraction are in the positive in sign or zero, that one of those results of the subtraction having the positive sign or the value of zero which corresponds to a highest one of the multiples is selected as a new intermediate remainder, whereafter the states of carry signals corresponding to the results of the subtraction are held. A processing cycle of the operations is repetitively executed by a plurality of times, and then a quotient is calculated in accordance with the held states of the carry signals. The dividing apparatus can be applied to division of a dividend by a divisor both in the form of decimal data in binary-coded decimal notation.
