We look at the division of 35931520 by 668 
Let's see how many times 668 fits into 35931520.

Let's proceed to step 1:
If we divide 3 by 668, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 668

Advancing to step 2:
When dividing 35 by 668, we get 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 668

Let's proceed to step 3:
The number 668 fits into 359 0 times, leaving a remainder of 359.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 359, we get 359.
Take the next digit (3) from the dividend and append it to 359, then repeat: 3593 / 668

Going ahead to step 4:
When dividing 3593 by 668, we get 5 with a remainder of 253.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 253 after subtracting 3340 from 3593.
Take the next digit (1) from the dividend and append it to 253, then repeat: 2531 / 668

Going ahead to step 5:
If we divide 2531 by 668, we get 3 and a remainder of 527.
The next digit of our result is 3. 
Result so far: 53.0
Deduct 2004 from 2531 and we're left with 527.
Append the next digit (5) from the dividend to 527 and continue with: 5275 / 668

Step 6:
668 goes into 5275 7 times with a remainder of 599.
The next digit of our result is 7. 
Result so far: 537.0
If we subtract 4676 from 5275, we get 599.
Grab the next digit (2) from the dividend, add it to 599, then carry on: 5992 / 668

Advancing to step 7:
668 can be fit into 5992 8 times, resulting in a remainder of 648.
Write down 8 as next digit of the result. 
Result so far: 5378.0
Subtracting 5344 from 5992 leaves us with 648.
Fetch the next digit (0) from the dividend, attach it to 648 and continue: 6480 / 668

Moving on to step 8:
668 goes into 6480 9 times with a remainder of 468.
Write down 9 as next digit of the result. 
Result so far: 53789.0
Deduct 6012 from 6480 and we're left 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 9:
668 goes into 4680 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 53789.7
If we subtract 4676 from 4680, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
The number 668 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 53789.7
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
If we divide 400 by 668, we get 0 and a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 53789.7
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 53789.7 with a remainder of 0.04.
