We look at the division of 42003696 by 520 
Let's see how many times 520 fits into 42003696.

Advancing to step 1:
520 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 520

Let's proceed to step 2:
If we divide 42 by 520, we get 0 and a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 520

On to step 3:
520 can be fit into 420 0 times, resulting in a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 420 and we're left with 420.
Append the next digit (0) from the dividend to 420 and continue with: 4200 / 520

Moving on to step 4:
4200 divided by 520 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 4160 from 4200 and we're left with 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 520

Advancing to step 5:
When dividing 403 by 520, we get 0 with a remainder of 403.
The next digit of our result is 0. 
Result so far: 80.0
Subtracting 0 from 403 leaves us with 403.
Fetch the next digit (6) from the dividend, attach it to 403 and continue: 4036 / 520

Step 6:
520 can be fit into 4036 7 times, resulting in a remainder of 396.
The next digit of our result is 7. 
Result so far: 807.0
The remainder is 396 after subtracting 3640 from 4036.
Fetch the next digit (9) from the dividend, attach it to 396 and continue: 3969 / 520

Moving on to step 7:
3969 divided by 520 is 7 with a remainder of 329.
The number 7 becomes the next digit in our result. 
Result so far: 8077.0
Subtract 3640 from 3969 to get 329.
Append the next digit (6) from the dividend to 329 and continue with: 3296 / 520

Let's proceed to step 8:
520 can be fit into 3296 6 times, resulting in a remainder of 176.
Write down 6 as next digit of the result. 
Result so far: 80776.0
If we subtract 3120 from 3296, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 9:
If we divide 1760 by 520, we get 3 and a remainder of 200.
Use 3 as the next digit of our solution. 
Result so far: 80776.3
If we subtract 1560 from 1760, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 10:
When dividing 2000 by 520, we get 3 with a remainder of 440.
Write down 3 as next digit of the result. 
Result so far: 80776.33
If we take 1560 away from 2000, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The quotient of the division is 80776.33, and the remainder is 0.44.
