We look at the division of 29804553 by 21 
Let's see how many times 21 fits into 29804553.

Going ahead to step 1:
21 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 21

Step 2:
The number 21 fits into 29 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 21 from 29 and we're left with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 21

Moving on to step 3:
If we divide 88 by 21, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 4 after subtracting 84 from 88.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 21

Advancing to step 4:
If we divide 40 by 21, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 141.0
If we take 21 away from 40, we end up with 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 21

On to step 5:
The number 21 fits into 194 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 1419.0
If we subtract 189 from 194, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 21

Step 6:
21 can be fit into 55 2 times, resulting in a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 14192.0
Deduct 42 from 55 and we're left with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 21

Advancing to step 7:
21 can be fit into 135 6 times, resulting in a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 141926.0
Deduct 126 from 135 and we're left with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 21

Advancing to step 8:
The number 21 fits into 93 4 times, leaving a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 1419264.0
If we subtract 84 from 93, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
21 can be fit into 90 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 1419264.4
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.

Step 10:
When dividing 60 by 21, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 1419264.42
Subtract 42 from 60 to 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 11:
When dividing 180 by 21, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 1419264.428
Subtracting 168 from 180 leaves us 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.

Moving on to step 12:
When dividing 120 by 21, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1419264.4285
Deduct 105 from 120 and we're left 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 13:
21 can be fit into 150 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 1419264.42857
If we take 147 away from 150, we end up 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.

Let's proceed to step 14:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1419264.428571
Subtracting 21 from 30 leaves us 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 15:
90 divided by 21 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1419264.4285714
Subtract 84 from 90 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.

Step 16:
If we divide 60 by 21, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 1419264.42857142
If we take 42 away from 60, we end up 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.

The final outcome is 1419264.42857142, with a leftover of 1.8e-08.
