We look at the division of 628011 by 21 
We want to divide 628011 by 21.

Advancing to step 1:
21 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 21

Going ahead to step 2:
When dividing 62 by 21, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 20 after subtracting 42 from 62.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 21

Step 3:
If we divide 208 by 21, we get 9 and a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Deduct 189 from 208 and we're left with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 21

Let's proceed to step 4:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 299.0
Subtracting 189 from 190 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 21

Moving on to step 5:
21 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 2990.0
Subtracting 0 from 11 leaves us with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 21

Advancing to step 6:
When dividing 111 by 21, we get 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 29905.0
Subtract 105 from 111 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
When dividing 60 by 21, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 29905.2
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
If we divide 180 by 21, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 29905.28
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
If we divide 120 by 21, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 29905.285
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
21 can be fit into 150 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 29905.2857
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
If we divide 30 by 21, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 29905.28571
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
If we divide 90 by 21, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 29905.285714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
60 divided by 21 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 29905.2857142
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 29905.28571428
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 29905.28571428 and a remainder of 1.2e-08.
