We look at the division of 31807256 by 520 
We want to divide 31807256 by 520.

Step 1:
520 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 520

On to step 2:
520 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 520

Step 3:
318 divided by 520 is 0 with a remainder of 318.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 318 to get 318.
Grab the next digit (0) from the dividend, add it to 318, then carry on: 3180 / 520

Going ahead to step 4:
If we divide 3180 by 520, we get 6 and a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 3120 from 3180, we get 60.
Append the next digit (7) from the dividend to 60 and continue with: 607 / 520

Advancing to step 5:
520 can be fit into 607 1 times, resulting in a remainder of 87.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
The remainder is 87 after subtracting 520 from 607.
Include the next digit (2) from the dividend after 87, then repeat: 872 / 520

Going ahead to step 6:
520 goes into 872 1 times with a remainder of 352.
Record the quotient 1 as the next digit in the result. 
Result so far: 611.0
Deduct 520 from 872 and we're left with 352.
Append the next digit (5) from the dividend to 352 and continue with: 3525 / 520

Step 7:
520 goes into 3525 6 times with a remainder of 405.
The number 6 becomes the next digit in our result. 
Result so far: 6116.0
If we subtract 3120 from 3525, we get 405.
Bring next digit (6) of the dividend behind the 405 and repeat the process: 4056 / 520

Advancing to step 8:
520 can be fit into 4056 7 times, resulting in a remainder of 416.
Put 7 as the next digit of the answer. 
Result so far: 61167.0
The remainder is 416 after subtracting 3640 from 4056.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 9:
4160 divided by 520 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 61167.8
Subtract 4160 from 4160 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
520 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 61167.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 520 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 61167.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 61167.8, and the remainder is 0.0.
