We look at the division of 39105027 by 520 
We want to divide 39105027 by 520.

On to step 1:
3 divided by 520 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 520

Going ahead to step 2:
If we divide 39 by 520, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 520

Moving on to step 3:
391 divided by 520 is 0 with a remainder of 391.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 391 leaves us with 391.
Include the next digit (0) from the dividend after 391, then repeat: 3910 / 520

Advancing to step 4:
If we divide 3910 by 520, we get 7 and a remainder of 270.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 3640 from 3910 leaves us with 270.
Append the next digit (5) from the dividend to 270 and continue with: 2705 / 520

Let's proceed to step 5:
If we divide 2705 by 520, we get 5 and a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtracting 2600 from 2705 leaves us with 105.
Bring next digit (0) of the dividend behind the 105 and repeat the process: 1050 / 520

Let's proceed to step 6:
When dividing 1050 by 520, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 752.0
Subtract 1040 from 1050 to get 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 520

On to step 7:
The number 520 fits into 102 0 times, leaving a remainder of 102.
Record the quotient 0 as the next digit in the result. 
Result so far: 7520.0
If we subtract 0 from 102, we get 102.
Grab the next digit (7) from the dividend, add it to 102, then carry on: 1027 / 520

On to step 8:
520 can be fit into 1027 1 times, resulting in a remainder of 507.
Record the quotient 1 as the next digit in the result. 
Result so far: 75201.0
The remainder is 507 after subtracting 520 from 1027.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Advancing to step 9:
5070 divided by 520 is 9 with a remainder of 390.
Write down 9 as next digit of the result. 
Result so far: 75201.9
Deduct 4680 from 5070 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 10:
3900 divided by 520 is 7 with a remainder of 260.
Write down 7 as next digit of the result. 
Result so far: 75201.97
The remainder is 260 after subtracting 3640 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 11:
520 can be fit into 2600 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 75201.975
Subtract 2600 from 2600 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.

Going ahead to step 12:
If we divide 0 by 520, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 75201.975
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
The number 520 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 75201.975
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.

In conclusion, the division gives 75201.975 with a balance of 0.0.
