SIMPLE DIVISION.

II. When the divisor has ciphers on the right of it, you
may strike them off, and divide without them ; but the same
number of figures must be struck off from the right of the
dividend, and affixed to the last remainder.

What is the quotient of 7380964 by 32000? Ans. 320] |gag
What is the quotient of 2304109 by 5800 ? Ans. 397 ‘4§&
III. Hence to divide by 1 with any number of ciphers
annexed, you need only strike off from the right-of the divi¬
dend so many figures as the divisor contains ciphers ; which
figures, so struck off, will be the remainder, and those on
the left the quotient.
Examples.
5138602 divided by 100 is equal to 51386rro*
2701483 by 1000 is

IV. When the divisor is the product of two or more small
numbers, it is much easier to divide continually by those
numbers, than by the whole divisor at once.
Note. If there be any remainders after such divisions, multiply th<
last remainder by the preceding divisor, and to the product add the re-|
mainder belonging to the same divisor; then multiply the sum by the
next preceding divisor, and to the product add its corresponding re¬
mainder ; proceed in the same manner through all the divisors and re¬
mainders , so shall the last sum be the remainder, the same as if the di.
vision had been performed at once.
After the operation described in this note is begun, it must be conti¬
nued according to.the description, though some of the preceding divi¬
sions should happen to have no remainder.
