We look at the division of 21835881 by 808 
We want to divide 21835881 by 808.

Step 1:
When dividing 2 by 808, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 808

Step 2:
The number 808 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 808

Step 3:
808 goes into 218 0 times with a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 218 and we're left with 218.
Take the next digit (3) from the dividend and append it to 218, then repeat: 2183 / 808

Going ahead to step 4:
2183 divided by 808 is 2 with a remainder of 567.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1616 from 2183 to get 567.
Fetch the next digit (5) from the dividend, attach it to 567 and continue: 5675 / 808

Step 5:
The number 808 fits into 5675 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtract 5656 from 5675 to get 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 808

Going ahead to step 6:
The number 808 fits into 198 0 times, leaving a remainder of 198.
The next digit of our result is 0. 
Result so far: 270.0
Deduct 0 from 198 and we're left with 198.
Append the next digit (8) from the dividend to 198 and continue with: 1988 / 808

Moving on to step 7:
When dividing 1988 by 808, we get 2 with a remainder of 372.
Record the quotient 2 as the next digit in the result. 
Result so far: 2702.0
Subtract 1616 from 1988 to get 372.
Fetch the next digit (1) from the dividend, attach it to 372 and continue: 3721 / 808

Going ahead to step 8:
808 can be fit into 3721 4 times, resulting in a remainder of 489.
The next digit of our result is 4. 
Result so far: 27024.0
Deduct 3232 from 3721 and we're left with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Going ahead to step 9:
If we divide 4890 by 808, we get 6 and a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 27024.6
If we subtract 4848 from 4890, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
The number 808 fits into 420 0 times, leaving a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 27024.6
The remainder is 420 after subtracting 0 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 11:
The number 808 fits into 4200 5 times, leaving a remainder of 160.
Put 5 as the next digit of the answer. 
Result so far: 27024.605
If we take 4040 away from 4200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
If we divide 1600 by 808, we get 1 and a remainder of 792.
The number 1 becomes the next digit in our result. 
Result so far: 27024.6051
If we subtract 808 from 1600, we get 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Moving on to step 13:
7920 divided by 808 is 9 with a remainder of 648.
Write down 9 as next digit of the result. 
Result so far: 27024.60519
If we subtract 7272 from 7920, we get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Step 14:
If we divide 6480 by 808, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 27024.605198
The remainder is 16 after subtracting 6464 from 6480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 15:
The number 808 fits into 160 0 times, leaving a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 27024.605198
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 16:
If we divide 1600 by 808, we get 1 and a remainder of 792.
The number 1 becomes the next digit in our result. 
Result so far: 27024.60519801
If we take 808 away from 1600, we end up with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

The final outcome is 27024.60519801, with a leftover of 7.92e-07.
