R I T H M E T I C K. 377 is 35, in which the divifor 7 is contained 5 times. Now vifor 8 below it, fignifying that 1 remains to be divided it is evident, that the fum of the partial qaots, 125, is by 8 ; or this part of the quotient may be confidered as the total quot, or a number exprelling how often the di- a fradlion, whofe numerator is 1, and its denominator 8 ; and the quotient thus completed Ihews, that the dividend 875 contains the divifor 7. From the above example we may learn, that there vidend contains the divifor 7004112 times, and one are always juft fo many figures in the quotient as there eighth part of a t are dividuals; or the firft dividual, with the number of Here obferve, that riot only the laft remainder, but fubfequent figures in the dividend, is equal to the num- every other remainder, muftbe lefs than the divifor ; for if it be either greater or equal, the divifor might have ber of places or figures in the quotient. Hence likewife may be inferred, that no divifor is been oftener got, and the quotient-figure is too little. contained in any dividual oftener than 9 times ; for the And ftiould any one in this cafe attempt to continue the dividual, excluding the right-hand figure, is always lefs operation, the quotient-figures would be all 9’s, the dithan the divifor by 1 at leaft ; and if both be multiplied viduals would prove inexhauftible, and the remaindeis by 10, or have a cipher annexed to each of them, the would conftantly increafe. produdt of the dividual will be lefs than the produd of Hence alfo learn, that if any dividual happen to be lefs the divifor by 10 at leaft ; but no right-hand figure can than the divifor, you muft put o in the quotient, and fupply this defed of 10; therefore the divifor is not bring down the next figure of the dividend ;»and if it be contained 10 times in any dividual, and confequently not ftill lefs than the divifor, you muft put another o in the oftener than 9 times. quotient, and bring down the following figure of the diHere too obferve, that the right-hand figure of the firft vidend, <bc. dividual, and all the fubfequent figures of the dividend, III.
