We look at the division of 204629 by 21 
We want to figure out the number of times 204629 can be divided by 21.

Going ahead to step 1:
If we divide 2 by 21, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 21

On to step 2:
When dividing 20 by 21, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 21

Advancing to step 3:
If we divide 204 by 21, we get 9 and a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 189 from 204, we get 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 21

Step 4:
21 can be fit into 156 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we take 147 away from 156, we end up with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 21

Let's proceed to step 5:
21 goes into 92 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 974.0
Subtract 84 from 92 to get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 21

Advancing to step 6:
21 can be fit into 89 4 times, resulting in a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 9744.0
Subtracting 84 from 89 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
21 goes into 50 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 9744.2
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
21 goes into 80 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 9744.23
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
When dividing 170 by 21, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 9744.238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
When dividing 20 by 21, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9744.238
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
21 can be fit into 200 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 9744.23809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 12:
If we divide 110 by 21, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 9744.238095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 9744.2380952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
If we divide 80 by 21, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 9744.23809523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 9744.23809523 with a balance of 1.7e-08.
