Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 2080 from 2503 leaves us with 423.
Fetch the next digit (9) from the dividend, attach it to 423 and continue: 4239 / 520

Moving on to step 5:
520 can be fit into 4239 8 times, resulting in a remainder of 79.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
Subtracting 4160 from 4239 leaves us with 79.
Grab the next digit (1) from the dividend, add it to 79, then carry on: 791 / 520

On to step 6:
The number 520 fits into 791 1 times, leaving a remainder of 271.
Put 1 as the next digit of the answer. 
Result so far: 1481.0
If we take 520 away from 791, we end up with 271.
Grab the next digit (6) from the dividend, add it to 271, then carry on: 2716 / 520

Step 7:
The number 520 fits into 2716 5 times, leaving a remainder of 116.
Use 5 as the next digit of our solution. 
Result so far: 14815.0
The remainder is 116 after subtracting 2600 from 2716.
Append the next digit (4) from the dividend to 116 and continue with: 1164 / 520

Going ahead to step 8:
If we divide 1164 by 520, we get 2 and a remainder of 124.
The number 2 becomes the next digit in our result. 
Result so far: 148152.0
Subtracting 1040 from 1164 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 9:
The number 520 fits into 1240 2 times, leaving a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 148152.2
If we subtract 1040 from 1240, 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.

Going ahead to step 10:
520 goes into 2000 3 times with a remainder of 440.
The number 3 becomes the next digit in our result. 
Result so far: 148152.23
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.

On to step 11:
520 goes into 4400 8 times with a remainder of 240.
Put 8 as the next digit of the answer. 
Result so far: 148152.238
Subtract 4160 from 4400 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 12:
2400 divided by 520 is 4 with a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 148152.2384
Deduct 2080 from 2400 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 13:
520 goes into 3200 6 times with a remainder of 80.
The next digit of our result is 6. 
Result so far: 148152.23846
The remainder is 80 after subtracting 3120 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
520 can be fit into 800 1 times, resulting in a remainder of 280.
The number 1 becomes the next digit in our result. 
Result so far: 148152.238461
Deduct 520 from 800 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 15:
The number 520 fits into 2800 5 times, leaving a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 148152.2384615
If we subtract 2600 from 2800, 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.

Going ahead to step 16:
If we divide 2000 by 520, we get 3 and a remainder of 440.
Put 3 as the next digit of the answer. 
Result so far: 148152.23846153
If we subtract 1560 from 2000, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

In conclusion, the division gives 148152.23846153 with a balance of 4.4e-07.
