We divide 21220 by 6
We want to figure out the number of times 21220 can be divided by 6.

Let's proceed to step 1:
2 divided by 6 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 6

Step 2:
The number 6 fits into 21 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 3 after subtracting 18 from 21.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 6

On to step 3:
The number 6 fits into 32 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we take 30 away from 32, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 6

Moving on to step 4:
6 goes into 22 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 353.0
If we take 18 away from 22, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 6

Step 5:
6 goes into 40 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 3536.0
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 6:
6 can be fit into 40 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 3536.6
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
40 divided by 6 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 3536.66
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 3536.66 with a remainder of 0.004.
