We look at the division of 68242431 by 520 
Our goal is to divide 68242431 by 520.

Going ahead to step 1:
520 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 520

Advancing to step 2:
520 can be fit into 68 0 times, resulting in a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Bring next digit (2) of the dividend behind the 68 and repeat the process: 682 / 520

On to step 3:
The number 520 fits into 682 1 times, leaving a remainder of 162.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 520 from 682, we get 162.
Append the next digit (4) from the dividend to 162 and continue with: 1624 / 520

Going ahead to step 4:
If we divide 1624 by 520, we get 3 and a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1560 from 1624 leaves us with 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 520

Going ahead to step 5:
When dividing 642 by 520, we get 1 with a remainder of 122.
Write down 1 as next digit of the result. 
Result so far: 131.0
If we subtract 520 from 642, we get 122.
Fetch the next digit (4) from the dividend, attach it to 122 and continue: 1224 / 520

Let's proceed to step 6:
When dividing 1224 by 520, we get 2 with a remainder of 184.
The next digit of our result is 2. 
Result so far: 1312.0
If we take 1040 away from 1224, we end up with 184.
Fetch the next digit (3) from the dividend, attach it to 184 and continue: 1843 / 520

Going ahead to step 7:
1843 divided by 520 is 3 with a remainder of 283.
Use 3 as the next digit of our solution. 
Result so far: 13123.0
Subtracting 1560 from 1843 leaves us with 283.
Include the next digit (1) from the dividend after 283, then repeat: 2831 / 520

Advancing to step 8:
2831 divided by 520 is 5 with a remainder of 231.
Put 5 as the next digit of the answer. 
Result so far: 131235.0
Deduct 2600 from 2831 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 9:
520 can be fit into 2310 4 times, resulting in a remainder of 230.
The next digit of our result is 4. 
Result so far: 131235.4
Subtracting 2080 from 2310 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 10:
2300 divided by 520 is 4 with a remainder of 220.
The number 4 becomes the next digit in our result. 
Result so far: 131235.44
The remainder is 220 after subtracting 2080 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The quotient of the division is 131235.44, and the remainder is 0.22.
