...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... | |

...examples, and observe the manner of working them. Proof. — Multiply the Quotient by the Divisor, or **the Divisor by the Quotient ; and to the Product, add the remainder,** the sum will be the same as the Dividend if the work be right. Divisor. Dividend. Quotient. Divisor.... | |

...divide this number as before, and continue dividing in the same manner till all the figures are divided. **PROOF. Multiply the divisor by the quotient, and to the product add the remainder,** and if the sum be equal to the dividend, it is supposed to be right. OBS. 1. The dividend, divisor,... | |

...which were cut off from the dividend. 29. To prove Division. Multiply the quotient by the divisor, or **the divisor by the quotient, and to the product add the remainder, if** there be one. The result ought to be the same as the dividend ; because we are only adding the divisor... | |

...cipher in the quotient, and annex the next figure, 7, making 27, which contains the divisor 9 times. **PROOF. — Multiply the divisor by the quotient, and to the product add the remainder,** and if the result be like the dividend, the work is right. Thus : Quotient 15609 Divisor 4)1486 Dividend.... | |

...the divisor underneath, with a line between them, at the right of the quotient. 74. first Method of **Proof. — Multiply the divisor by the quotient, and to the product add the remainder, if any,** and if the work be right, the sum thus obtained will be equal to the dividend. NOTE. — This method... | |
