10812579 ÷ 520 
Our goal is to divide 10812579 by 520.

Going ahead to step 1:
1 divided by 520 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 520

Let's proceed to step 2:
The number 520 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 520

On to step 3:
108 divided by 520 is 0 with a remainder of 108.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 108 and we're left with 108.
Include the next digit (1) from the dividend after 108, then repeat: 1081 / 520

Advancing to step 4:
520 goes into 1081 2 times with a remainder of 41.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1040 from 1081, we get 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 520

Advancing to step 5:
If we divide 412 by 520, we get 0 and a remainder of 412.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtracting 0 from 412 leaves us with 412.
Bring next digit (5) of the dividend behind the 412 and repeat the process: 4125 / 520

Step 6:
When dividing 4125 by 520, we get 7 with a remainder of 485.
Write down 7 as next digit of the result. 
Result so far: 207.0
If we take 3640 away from 4125, we end up with 485.
Take the next digit (7) from the dividend and append it to 485, then repeat: 4857 / 520

Let's proceed to step 7:
520 goes into 4857 9 times with a remainder of 177.
Use 9 as the next digit of our solution. 
Result so far: 2079.0
Deduct 4680 from 4857 and we're left with 177.
Take the next digit (9) from the dividend and append it to 177, then repeat: 1779 / 520

Let's proceed to step 8:
1779 divided by 520 is 3 with a remainder of 219.
Write down 3 as next digit of the result. 
Result so far: 20793.0
Subtracting 1560 from 1779 leaves us with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Step 9:
2190 divided by 520 is 4 with a remainder of 110.
The next digit of our result is 4. 
Result so far: 20793.4
If we take 2080 away from 2190, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
When dividing 1100 by 520, we get 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 20793.42
Subtracting 1040 from 1100 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
The number 520 fits into 600 1 times, leaving a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 20793.421
If we take 520 away from 600, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
If we divide 800 by 520, we get 1 and a remainder of 280.
Use 1 as the next digit of our solution. 
Result so far: 20793.4211
If we subtract 520 from 800, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Our division results in 20793.4211 with a remaining 0.0028.
