In the picture, 6.84 divided by 2 is equal to 3.42; 6.84: 2 = 3. 42
To divide a whole number by 10, we quit one zero. Example: 70: 10 = 7
To divide a whole number by 100, we quit two zeros. Example: 800: 100 = 8
To divide a whole number by 1000, we quit three zeros. Example: 5000: 1000 = 5
Solve these divisions:
20 : 10 = 

4000 : 100 = 

12000 : 1000 = 

1500 : 100 = 

10000 : 1000 = 
To divide a whole number by 10, we move the decimal point one place to the left.
Example: 26:10 = 2.6
To divide a whole number by 100, we move the decimal point two places to the left.
Example: 809:100 = 8, 09
To divide a whole number by 1000, we move the decimal point three places to the left.
Example: 5437:1000 = 5,437
8 : 10 = 

123000 : 10 = 

1027 : 100 = 

6324 : 1000 = 

254 : 100 = 
To divide a decimal number by a natural number, we must ignore the decimal point and make the division as if the dividend and the divisor are natural numbers. Then we put the decimal point in the quotient.
Example 7,32 _4___
33 1,83
12
0
