When dividing a decimal by an integer, use either a short division or long division method, making sure that the decimal point on the answer line is above the decimal point for the number being divided.

If the number does not divide exactly, add zeroes to the end of the number being divided to obtain the required accuracy: 95.60 is the same as 95.6.

Dividing a number by a decimal should be avoided. A division can be written as a fraction with the divisor as the denominator: multiply both numbers by 10, 100 or 1000 to remove the decimal from the denominator. Multiplying both the numerator *and* the denominator by the same amount gives an equivalent fraction.

1. Calculate 17.15 ÷ 7.

Answer: 2.45

2. A bottling plant is bottling a new perfume, and is producing some sample bottles for distribution. It has allocated 34 litres for the promotion, and each sample bottle can hold 0.08 litres. How many bottles are needed for the promotion?

Answer: 425

This is a division. Start by multiplying the two numbers by 100 to turn the divisor into an integer.

`frac(34)(0.08)` = `frac(3400)(8)` = 425
