We're dividing 21817431 by 684 
We want to divide 21817431 by 684.

Moving on to step 1:
If we divide 2 by 684, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 684

Advancing to step 2:
If we divide 21 by 684, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 684

Going ahead to step 3:
218 divided by 684 is 0 with a remainder of 218.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 218, we get 218.
Grab the next digit (1) from the dividend, add it to 218, then carry on: 2181 / 684

Advancing to step 4:
The number 684 fits into 2181 3 times, leaving a remainder of 129.
The next digit of our result is 3. 
Result so far: 3.0
If we take 2052 away from 2181, we end up with 129.
Take the next digit (7) from the dividend and append it to 129, then repeat: 1297 / 684

Let's proceed to step 5:
1297 divided by 684 is 1 with a remainder of 613.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 684 from 1297, we get 613.
Fetch the next digit (4) from the dividend, attach it to 613 and continue: 6134 / 684

Let's proceed to step 6:
684 can be fit into 6134 8 times, resulting in a remainder of 662.
The next digit of our result is 8. 
Result so far: 318.0
The remainder is 662 after subtracting 5472 from 6134.
Grab the next digit (3) from the dividend, add it to 662, then carry on: 6623 / 684

Moving on to step 7:
684 goes into 6623 9 times with a remainder of 467.
The next digit of our result is 9. 
Result so far: 3189.0
The remainder is 467 after subtracting 6156 from 6623.
Take the next digit (1) from the dividend and append it to 467, then repeat: 4671 / 684

Moving on to step 8:
684 can be fit into 4671 6 times, resulting in a remainder of 567.
Use 6 as the next digit of our solution. 
Result so far: 31896.0
Subtracting 4104 from 4671 leaves us with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Moving on to step 9:
5670 divided by 684 is 8 with a remainder of 198.
The next digit of our result is 8. 
Result so far: 31896.8
Deduct 5472 from 5670 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 10:
1980 divided by 684 is 2 with a remainder of 612.
Use 2 as the next digit of our solution. 
Result so far: 31896.82
The remainder is 612 after subtracting 1368 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Let's proceed to step 11:
6120 divided by 684 is 8 with a remainder of 648.
Put 8 as the next digit of the answer. 
Result so far: 31896.828
Subtract 5472 from 6120 to 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.

Advancing to step 12:
684 goes into 6480 9 times with a remainder of 324.
Put 9 as the next digit of the answer. 
Result so far: 31896.8289
If we take 6156 away from 6480, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 13:
If we divide 3240 by 684, we get 4 and a remainder of 504.
Write down 4 as next digit of the result. 
Result so far: 31896.82894
Deduct 2736 from 3240 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Moving on to step 14:
684 can be fit into 5040 7 times, resulting in a remainder of 252.
Record the quotient 7 as the next digit in the result. 
Result so far: 31896.828947
Subtracting 4788 from 5040 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 15:
When dividing 2520 by 684, we get 3 with a remainder of 468.
The number 3 becomes the next digit in our result. 
Result so far: 31896.8289473
If we take 2052 away from 2520, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 16:
The number 684 fits into 4680 6 times, leaving a remainder of 576.
Write down 6 as next digit of the result. 
Result so far: 31896.82894736
If we subtract 4104 from 4680, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The final result is 31896.82894736 with a remainder of 5.76e-07.
