...If this sum be less than the divisor, place a cipher in the quotient, and bring down another figure. Proof. Multiply the divisor by the quotient, and to the product add the remainder, if any, and if the sum equal the dividend, the work it right. Examples. 1. Divide 147 by 4. Having written... | |
