Norf..- after bringing down a figure to the remainder, i: be still less than the divisor, place a cipher in the quotient, and bring down another figure. Should it still be too small, write another" cipher in eine quotient, and bring down another figure, and so on till the number shall contain the divisor.
PROOF. 107. Multiply the divisor by the quotient, (adding the re mainder, if any) and, if it be right, the product will be equal to the dividend.

remains, to be joined to the 6, making 26. Then -3 in 26,8 times, and 2 over. We write 8 for the next figure of the quotient, and place 2 before the 7, making 27, in which we find 3, 9 times. We therefore place 9 in the unit's place of the quotient, and the work is done. Division performed in this manner, without writing down the whole operation, is called Short Division.

As it will take 10 apples to give each child 1, each child will evidently receive as many appiles as there are 10's in the whole number'; but all the figures of any number, tisken lugether, may be regarded as tens, excepting that which is in the unit's place. 'l'he 4 then is the quotient, and the õ is the remainiler; that is, 45 apples will give 10 children 4 apples and 5 tenths, or each. And as all the figures of a number, higher than in the ten's place, may be considereil lundreds, we may in like manner divide by 100, by culling off two figures from the right of the dividend; and, generally,
