We're dividing 28239631 by 520 
We want to divide 28239631 by 520.

Moving on to step 1:
When dividing 2 by 520, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 520

Step 2:
28 divided by 520 is 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 520

Moving on to step 3:
The number 520 fits into 282 0 times, leaving a remainder of 282.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 282 and we're left with 282.
Take the next digit (3) from the dividend and append it to 282, then repeat: 2823 / 520

On to step 4:
520 can be fit into 2823 5 times, resulting in a remainder of 223.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 2600 from 2823 leaves us with 223.
Bring next digit (9) of the dividend behind the 223 and repeat the process: 2239 / 520

Advancing to step 5:
2239 divided by 520 is 4 with a remainder of 159.
Write down 4 as next digit of the result. 
Result so far: 54.0
If we take 2080 away from 2239, we end up with 159.
Grab the next digit (6) from the dividend, add it to 159, then carry on: 1596 / 520

Step 6:
If we divide 1596 by 520, we get 3 and a remainder of 36.
The next digit of our result is 3. 
Result so far: 543.0
If we take 1560 away from 1596, we end up with 36.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 520

Going ahead to step 7:
The number 520 fits into 363 0 times, leaving a remainder of 363.
Use 0 as the next digit of our solution. 
Result so far: 5430.0
If we subtract 0 from 363, we get 363.
Append the next digit (1) from the dividend to 363 and continue with: 3631 / 520

Let's proceed to step 8:
When dividing 3631 by 520, we get 6 with a remainder of 511.
The next digit of our result is 6. 
Result so far: 54306.0
If we take 3120 away from 3631, we end up with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

On to step 9:
The number 520 fits into 5110 9 times, leaving a remainder of 430.
Write down 9 as next digit of the result. 
Result so far: 54306.9
Subtracting 4680 from 5110 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 10:
520 can be fit into 4300 8 times, resulting in a remainder of 140.
Use 8 as the next digit of our solution. 
Result so far: 54306.98
Subtract 4160 from 4300 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 11:
The number 520 fits into 1400 2 times, leaving a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 54306.982
If we take 1040 away from 1400, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 12:
When dividing 3600 by 520, we get 6 with a remainder of 480.
Use 6 as the next digit of our solution. 
Result so far: 54306.9826
Deduct 3120 from 3600 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 13:
4800 divided by 520 is 9 with a remainder of 120.
Use 9 as the next digit of our solution. 
Result so far: 54306.98269
The remainder is 120 after subtracting 4680 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 14:
The number 520 fits into 1200 2 times, leaving a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 54306.982692
Subtracting 1040 from 1200 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
If we divide 1600 by 520, we get 3 and a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 54306.9826923
Subtract 1560 from 1600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 16:
520 goes into 400 0 times with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 54306.9826923
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 54306.9826923 with a remainder of 4e-07.
