A dividing device includes: shifting circuits which left-shift the mantissa parts of the dividend and the divisor by a first and a second count values; a digit number arithmetic circuit which calculates a quotient digit number expected value based on the first count value and the second count value; a dividing circuit which outputs a quotient and a remainder in sequence on a digit-by-digit basis based on the mantissa parts of the dividend and the divisor left-shifted by the shifting circuits; a subtracting circuit which subtracts an exponent part of the floating-point number being the divisor from an exponent part of the floating-point number being the dividend to output a resultant value; and a control circuit which outputs a mantissa part and an exponent part of a floating-point number being a quotient. |
