We look at the division of 23518684 by 999 
We want to divide 23518684 by 999.

Let's proceed to step 1:
2 divided by 999 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 999

Advancing to step 2:
The number 999 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 999

Let's proceed to step 3:
235 divided by 999 is 0 with a remainder of 235.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 235 to get 235.
Bring next digit (1) of the dividend behind the 235 and repeat the process: 2351 / 999

On to step 4:
When dividing 2351 by 999, we get 2 with a remainder of 353.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1998 from 2351 and we're left with 353.
Grab the next digit (8) from the dividend, add it to 353, then carry on: 3538 / 999

Going ahead to step 5:
999 can be fit into 3538 3 times, resulting in a remainder of 541.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 2997 from 3538, we get 541.
Append the next digit (6) from the dividend to 541 and continue with: 5416 / 999

Going ahead to step 6:
999 goes into 5416 5 times with a remainder of 421.
The number 5 becomes the next digit in our result. 
Result so far: 235.0
Subtracting 4995 from 5416 leaves us with 421.
Include the next digit (8) from the dividend after 421, then repeat: 4218 / 999

Step 7:
4218 divided by 999 is 4 with a remainder of 222.
Use 4 as the next digit of our solution. 
Result so far: 2354.0
If we subtract 3996 from 4218, we get 222.
Grab the next digit (4) from the dividend, add it to 222, then carry on: 2224 / 999

Step 8:
If we divide 2224 by 999, we get 2 and a remainder of 226.
The next digit of our result is 2. 
Result so far: 23542.0
Deduct 1998 from 2224 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 9:
2260 divided by 999 is 2 with a remainder of 262.
Use 2 as the next digit of our solution. 
Result so far: 23542.2
If we take 1998 away from 2260, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 10:
999 can be fit into 2620 2 times, resulting in a remainder of 622.
The number 2 becomes the next digit in our result. 
Result so far: 23542.22
The remainder is 622 after subtracting 1998 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Our division results in 23542.22 with a remaining 0.622.
