We look at the division of 21485352 by 681 
Let's see how many times 681 fits into 21485352.

Moving on to step 1:
2 divided by 681 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 681

Going ahead to step 2:
681 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 681

Moving on to step 3:
If we divide 214 by 681, we get 0 and a remainder of 214.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 214 leaves us with 214.
Fetch the next digit (8) from the dividend, attach it to 214 and continue: 2148 / 681

Let's proceed to step 4:
When dividing 2148 by 681, we get 3 with a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2043 from 2148 and we're left with 105.
Include the next digit (5) from the dividend after 105, then repeat: 1055 / 681

Step 5:
If we divide 1055 by 681, we get 1 and a remainder of 374.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtracting 681 from 1055 leaves us with 374.
Take the next digit (3) from the dividend and append it to 374, then repeat: 3743 / 681

Let's proceed to step 6:
When dividing 3743 by 681, we get 5 with a remainder of 338.
Write down 5 as next digit of the result. 
Result so far: 315.0
Deduct 3405 from 3743 and we're left with 338.
Take the next digit (5) from the dividend and append it to 338, then repeat: 3385 / 681

On to step 7:
The number 681 fits into 3385 4 times, leaving a remainder of 661.
The next digit of our result is 4. 
Result so far: 3154.0
Subtract 2724 from 3385 to get 661.
Include the next digit (2) from the dividend after 661, then repeat: 6612 / 681

Going ahead to step 8:
681 can be fit into 6612 9 times, resulting in a remainder of 483.
Use 9 as the next digit of our solution. 
Result so far: 31549.0
If we subtract 6129 from 6612, we get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Advancing to step 9:
When dividing 4830 by 681, we get 7 with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 31549.7
If we subtract 4767 from 4830, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 10:
681 goes into 630 0 times with a remainder of 630.
Record the quotient 0 as the next digit in the result. 
Result so far: 31549.7
If we subtract 0 from 630, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 11:
When dividing 6300 by 681, we get 9 with a remainder of 171.
Use 9 as the next digit of our solution. 
Result so far: 31549.709
Subtract 6129 from 6300 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Advancing to step 12:
1710 divided by 681 is 2 with a remainder of 348.
The next digit of our result is 2. 
Result so far: 31549.7092
Deduct 1362 from 1710 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 13:
681 can be fit into 3480 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 31549.70925
If we take 3405 away from 3480, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 14:
The number 681 fits into 750 1 times, leaving a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 31549.709251
The remainder is 69 after subtracting 681 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 15:
690 divided by 681 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 31549.7092511
Subtract 681 from 690 to 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.

The final result is 31549.7092511 with a remainder of 9e-08.
