We look at the division of 655333 by 21 
We want to figure out the number of times 655333 can be divided by 21.

On to step 1:
6 divided by 21 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 21

Advancing to step 2:
65 divided by 21 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 63 from 65, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 21

Advancing to step 3:
21 can be fit into 25 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 21 from 25, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 21

Step 4:
If we divide 43 by 21, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 312.0
If we take 42 away from 43, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 21

Moving on to step 5:
If we divide 13 by 21, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 3120.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 21

Going ahead to step 6:
If we divide 133 by 21, we get 6 and a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 31206.0
If we take 126 away from 133, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
21 goes into 70 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 31206.3
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
When dividing 70 by 21, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 31206.33
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 31206.33 with a balance of 0.007.
