We look at the division of 23635840 by 668 
We want to figure out the number of times 23635840 can be divided by 668.

Going ahead to step 1:
2 divided by 668 is 0 with a remainder of 2.
The next digit of our result is 0. 
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 / 668

Going ahead to step 2:
If we divide 23 by 668, we get 0 and a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Fetch the next digit (6) from the dividend, attach it to 23 and continue: 236 / 668

Step 3:
668 goes into 236 0 times with a remainder of 236.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 236 leaves us with 236.
Include the next digit (3) from the dividend after 236, then repeat: 2363 / 668

Moving on to step 4:
If we divide 2363 by 668, we get 3 and a remainder of 359.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 2004 from 2363 to get 359.
Include the next digit (5) from the dividend after 359, then repeat: 3595 / 668

On to step 5:
If we divide 3595 by 668, we get 5 and a remainder of 255.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 255 after subtracting 3340 from 3595.
Include the next digit (8) from the dividend after 255, then repeat: 2558 / 668

Going ahead to step 6:
668 goes into 2558 3 times with a remainder of 554.
The next digit of our result is 3. 
Result so far: 353.0
Deduct 2004 from 2558 and we're left with 554.
Fetch the next digit (4) from the dividend, attach it to 554 and continue: 5544 / 668

On to step 7:
If we divide 5544 by 668, we get 8 and a remainder of 200.
The number 8 becomes the next digit in our result. 
Result so far: 3538.0
If we take 5344 away from 5544, we end up with 200.
Bring next digit (0) of the dividend behind the 200 and repeat the process: 2000 / 668

Going ahead to step 8:
When dividing 2000 by 668, we get 2 with a remainder of 664.
Record the quotient 2 as the next digit in the result. 
Result so far: 35382.0
The remainder is 664 after subtracting 1336 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Let's proceed to step 9:
The number 668 fits into 6640 9 times, leaving a remainder of 628.
The next digit of our result is 9. 
Result so far: 35382.9
If we take 6012 away from 6640, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Advancing to step 10:
When dividing 6280 by 668, we get 9 with a remainder of 268.
The next digit of our result is 9. 
Result so far: 35382.99
If we take 6012 away from 6280, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final result is 35382.99 with a remainder of 0.268.
