We look at the division of 87139808 by 517 
We're looking to find how many times 517 goes into 87139808.

Advancing to step 1:
517 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 517

Let's proceed to step 2:
87 divided by 517 is 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 517

Going ahead to step 3:
When dividing 871 by 517, we get 1 with a remainder of 354.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 517 from 871 to get 354.
Append the next digit (3) from the dividend to 354 and continue with: 3543 / 517

Going ahead to step 4:
When dividing 3543 by 517, we get 6 with a remainder of 441.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 3102 from 3543 leaves us with 441.
Include the next digit (9) from the dividend after 441, then repeat: 4419 / 517

Step 5:
If we divide 4419 by 517, we get 8 and a remainder of 283.
Use 8 as the next digit of our solution. 
Result so far: 168.0
The remainder is 283 after subtracting 4136 from 4419.
Fetch the next digit (8) from the dividend, attach it to 283 and continue: 2838 / 517

Going ahead to step 6:
517 goes into 2838 5 times with a remainder of 253.
Record the quotient 5 as the next digit in the result. 
Result so far: 1685.0
If we subtract 2585 from 2838, we get 253.
Grab the next digit (0) from the dividend, add it to 253, then carry on: 2530 / 517

Let's proceed to step 7:
517 goes into 2530 4 times with a remainder of 462.
Record the quotient 4 as the next digit in the result. 
Result so far: 16854.0
The remainder is 462 after subtracting 2068 from 2530.
Take the next digit (8) from the dividend and append it to 462, then repeat: 4628 / 517

On to step 8:
If we divide 4628 by 517, we get 8 and a remainder of 492.
The next digit of our result is 8. 
Result so far: 168548.0
Subtracting 4136 from 4628 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 9:
517 can be fit into 4920 9 times, resulting in a remainder of 267.
Record the quotient 9 as the next digit in the result. 
Result so far: 168548.9
If we subtract 4653 from 4920, we get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 10:
When dividing 2670 by 517, we get 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 168548.95
Deduct 2585 from 2670 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 11:
If we divide 850 by 517, we get 1 and a remainder of 333.
Write down 1 as next digit of the result. 
Result so far: 168548.951
Subtracting 517 from 850 leaves us with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Going ahead to step 12:
If we divide 3330 by 517, we get 6 and a remainder of 228.
Write down 6 as next digit of the result. 
Result so far: 168548.9516
Deduct 3102 from 3330 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 13:
2280 divided by 517 is 4 with a remainder of 212.
The next digit of our result is 4. 
Result so far: 168548.95164
If we subtract 2068 from 2280, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 14:
If we divide 2120 by 517, we get 4 and a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 168548.951644
If we take 2068 away from 2120, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 168548.951644 with a balance of 5.2e-06.
