We look at the division of 86131379 by 519 
We want to figure out the number of times 86131379 can be divided by 519.

Going ahead to step 1:
8 divided by 519 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 519

Advancing to step 2:
86 divided by 519 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Fetch the next digit (1) from the dividend, attach it to 86 and continue: 861 / 519

Advancing to step 3:
519 goes into 861 1 times with a remainder of 342.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 519 away from 861, we end up with 342.
Fetch the next digit (3) from the dividend, attach it to 342 and continue: 3423 / 519

Advancing to step 4:
519 goes into 3423 6 times with a remainder of 309.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 3114 from 3423, we get 309.
Fetch the next digit (1) from the dividend, attach it to 309 and continue: 3091 / 519

Going ahead to step 5:
3091 divided by 519 is 5 with a remainder of 496.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
Deduct 2595 from 3091 and we're left with 496.
Append the next digit (3) from the dividend to 496 and continue with: 4963 / 519

Moving on to step 6:
The number 519 fits into 4963 9 times, leaving a remainder of 292.
The next digit of our result is 9. 
Result so far: 1659.0
If we take 4671 away from 4963, we end up with 292.
Fetch the next digit (7) from the dividend, attach it to 292 and continue: 2927 / 519

On to step 7:
519 can be fit into 2927 5 times, resulting in a remainder of 332.
Write down 5 as next digit of the result. 
Result so far: 16595.0
Deduct 2595 from 2927 and we're left with 332.
Fetch the next digit (9) from the dividend, attach it to 332 and continue: 3329 / 519

Advancing to step 8:
The number 519 fits into 3329 6 times, leaving a remainder of 215.
Put 6 as the next digit of the answer. 
Result so far: 165956.0
If we take 3114 away from 3329, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 9:
If we divide 2150 by 519, we get 4 and a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 165956.4
The remainder is 74 after subtracting 2076 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
When dividing 740 by 519, we get 1 with a remainder of 221.
The number 1 becomes the next digit in our result. 
Result so far: 165956.41
Deduct 519 from 740 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 11:
519 goes into 2210 4 times with a remainder of 134.
Write down 4 as next digit of the result. 
Result so far: 165956.414
Deduct 2076 from 2210 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 12:
The number 519 fits into 1340 2 times, leaving a remainder of 302.
Record the quotient 2 as the next digit in the result. 
Result so far: 165956.4142
Deduct 1038 from 1340 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 13:
3020 divided by 519 is 5 with a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 165956.41425
Deduct 2595 from 3020 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 14:
519 goes into 4250 8 times with a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 165956.414258
Subtracting 4152 from 4250 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 15:
519 goes into 980 1 times with a remainder of 461.
Write down 1 as next digit of the result. 
Result so far: 165956.4142581
Subtract 519 from 980 to get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Advancing to step 16:
4610 divided by 519 is 8 with a remainder of 458.
Use 8 as the next digit of our solution. 
Result so far: 165956.41425818
If we subtract 4152 from 4610, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

The final result is 165956.41425818 with a remainder of 4.58e-07.
