We're dividing 15169020 by 520 
Our goal is to divide 15169020 by 520.

Going ahead to step 1:
If we divide 1 by 520, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 520

Advancing to step 2:
15 divided by 520 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 520

Let's proceed to step 3:
If we divide 151 by 520, we get 0 and a remainder of 151.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 151 to get 151.
Fetch the next digit (6) from the dividend, attach it to 151 and continue: 1516 / 520

Let's proceed to step 4:
520 goes into 1516 2 times with a remainder of 476.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 476 after subtracting 1040 from 1516.
Bring next digit (9) of the dividend behind the 476 and repeat the process: 4769 / 520

Advancing to step 5:
520 can be fit into 4769 9 times, resulting in a remainder of 89.
The next digit of our result is 9. 
Result so far: 29.0
If we subtract 4680 from 4769, we get 89.
Grab the next digit (0) from the dividend, add it to 89, then carry on: 890 / 520

Going ahead to step 6:
The number 520 fits into 890 1 times, leaving a remainder of 370.
Use 1 as the next digit of our solution. 
Result so far: 291.0
Subtract 520 from 890 to get 370.
Fetch the next digit (2) from the dividend, attach it to 370 and continue: 3702 / 520

Moving on to step 7:
3702 divided by 520 is 7 with a remainder of 62.
Use 7 as the next digit of our solution. 
Result so far: 2917.0
If we subtract 3640 from 3702, we get 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 520

Moving on to step 8:
520 goes into 620 1 times with a remainder of 100.
The number 1 becomes the next digit in our result. 
Result so far: 29171.0
If we subtract 520 from 620, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 9:
When dividing 1000 by 520, we get 1 with a remainder of 480.
The next digit of our result is 1. 
Result so far: 29171.1
Subtract 520 from 1000 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 10:
If we divide 4800 by 520, we get 9 and a remainder of 120.
Use 9 as the next digit of our solution. 
Result so far: 29171.19
Subtract 4680 from 4800 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
If we divide 1200 by 520, we get 2 and a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 29171.192
Deduct 1040 from 1200 and we're left 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.

Let's proceed to step 12:
When dividing 1600 by 520, we get 3 with a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 29171.1923
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 13:
If we divide 400 by 520, we get 0 and a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 29171.1923
If we take 0 away from 400, we end up 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.

Step 14:
The number 520 fits into 4000 7 times, leaving a remainder of 360.
The next digit of our result is 7. 
Result so far: 29171.192307
Subtract 3640 from 4000 to get 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 15:
If we divide 3600 by 520, we get 6 and a remainder of 480.
The next digit of our result is 6. 
Result so far: 29171.1923076
Subtract 3120 from 3600 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 16:
520 goes into 4800 9 times with a remainder of 120.
The next digit of our result is 9. 
Result so far: 29171.19230769
Subtracting 4680 from 4800 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 29171.19230769 with a remainder of 1.2e-07.
