# Dividing a whole number by a decimal

Dividing a whole number by a decimal can be simplified by multiplying both numbers by 10, shifting the decimal point to the right. For example, dividing 518 by 0.7 becomes 5,180 divided by 7. Using long division, the result is 740, making the process easier and more manageable. Created by Sal Khan.

• is it possible to make 1000000000000000 in a fraction
• I think so it would be like 1000000000000000/1
• Why is there a green dot in the center in the whole video?
• at do you need the zeros
• Since adding as many zeroes as wanted behind the decimal point (for example 7 = 7.0000000) never changes the number, one can do it. You don't need the zeroes, but the problem is a lot easier if you add them.
• I have a math problem it is 40 divided by 1.25. This video didn't really help me with this problem but if any of you guys know how to help me please leave a comment. Thanks
• Just move the decimal 2 places to the right so it becomes 4000 divided by 125.
• Is there an easier way of doing this math, or any helpful tips?
• Here are tricks for dividing by some common decimals.

1. Dividing by 0.5 is the same as multiplying by 2.

2. Dividing by 0.25 is the same as multiplying by 4.

3. Dividing by 0.2 is the same as multiplying by 5.

4. Dividing by 0.1 is the same as multiplying by 10.

5. Dividing by 0.05 is the same as multiplying by 20.

6. Dividing by 0.02 is the same as multiplying by 50.
