• Division by 10, 100, and 1,000

To divide by 10, 100, 1,000, and so on, move the decimal point to the left

in the dividend as many places as there are zeroes in the divisor.

1. Dividing by 10

Example 1: ₱8450 = ₱845.0, = ₱845.00
10

Example 2: ₱84.50 = ₱8.4.50 = ₱8.45
10

Note: Move the decimal point one place to the left.

2. Dividing by 100

Example 1: ₱8450 = ₱84.50. = ₱84.50
100

Example 2: ₱84.50 = ₱. 84.50 = ₱0.845
100

Note: Move the decimal point two places to the left.

3. Dividing by 1,000

Example 1: ₱74750 = ₱ 74.750. = ₱74.75
1000

Example 2: ₱747.00 = ₱. 747.50. = ₱0.7475
1,000

Example 3: ₱7.47 = ₱. 00747 = ₱0.00747
1000

Note: Move the decimal point three places to the left.

• The Whole Number Divisor

When the dividend contains a decimal and the divisor is a whole number,
the decimal point in the quotient is placed directly above the decimal point in the

dividend.

2.65

Example 1: 23.40 The decimal point Example 2:

6 | 140.40 in the quotient 5 | 13.25
12 . 23.40 is placed 10 . Notice the
20 directly above the 3 2 position of the
18 . decimal point in 3 0 . decimal points.
2 4 the dividend, 25
