We're dividing 21852759 by 687 
We want to divide 21852759 by 687.

Moving on to step 1:
When dividing 2 by 687, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 687

Advancing to step 2:
If we divide 21 by 687, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 687

Step 3:
218 divided by 687 is 0 with a remainder of 218.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 218 leaves us with 218.
Grab the next digit (5) from the dividend, add it to 218, then carry on: 2185 / 687

On to step 4:
The number 687 fits into 2185 3 times, leaving a remainder of 124.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 2061 from 2185, we get 124.
Fetch the next digit (2) from the dividend, attach it to 124 and continue: 1242 / 687

Let's proceed to step 5:
If we divide 1242 by 687, we get 1 and a remainder of 555.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 687 from 1242 leaves us with 555.
Append the next digit (7) from the dividend to 555 and continue with: 5557 / 687

Going ahead to step 6:
687 can be fit into 5557 8 times, resulting in a remainder of 61.
Record the quotient 8 as the next digit in the result. 
Result so far: 318.0
Deduct 5496 from 5557 and we're left with 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 687

Going ahead to step 7:
687 goes into 615 0 times with a remainder of 615.
Write down 0 as next digit of the result. 
Result so far: 3180.0
Subtract 0 from 615 to get 615.
Bring next digit (9) of the dividend behind the 615 and repeat the process: 6159 / 687

Moving on to step 8:
When dividing 6159 by 687, we get 8 with a remainder of 663.
The number 8 becomes the next digit in our result. 
Result so far: 31808.0
If we take 5496 away from 6159, we end up with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Let's proceed to step 9:
The number 687 fits into 6630 9 times, leaving a remainder of 447.
Use 9 as the next digit of our solution. 
Result so far: 31808.9
Subtract 6183 from 6630 to get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Step 10:
4470 divided by 687 is 6 with a remainder of 348.
Use 6 as the next digit of our solution. 
Result so far: 31808.96
Subtract 4122 from 4470 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 11:
687 can be fit into 3480 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 31808.965
If we take 3435 away from 3480, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 12:
If we divide 450 by 687, we get 0 and a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 31808.965
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 13:
When dividing 4500 by 687, we get 6 with a remainder of 378.
Use 6 as the next digit of our solution. 
Result so far: 31808.96506
If we take 4122 away from 4500, we end up with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 14:
687 goes into 3780 5 times with a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 31808.965065
If we take 3435 away from 3780, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 15:
687 goes into 3450 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 31808.9650655
If we take 3435 away from 3450, we end up 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.

The final outcome is 31808.9650655, with a leftover of 1.5e-07.
