515792 divided by 86 
The aim is to understand the frequency of 86 in 515792.

Advancing to step 1:
When dividing 5 by 86, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 86

Let's proceed to step 2:
51 divided by 86 is 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 86

Let's proceed to step 3:
When dividing 515 by 86, we get 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 430 away from 515, we end up with 85.
Include the next digit (7) from the dividend after 85, then repeat: 857 / 86

Going ahead to step 4:
If we divide 857 by 86, we get 9 and a remainder of 83.
Write down 9 as next digit of the result. 
Result so far: 59.0
Subtracting 774 from 857 leaves us with 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 86

Going ahead to step 5:
The number 86 fits into 839 9 times, leaving a remainder of 65.
The next digit of our result is 9. 
Result so far: 599.0
The remainder is 65 after subtracting 774 from 839.
Grab the next digit (2) from the dividend, add it to 65, then carry on: 652 / 86

Let's proceed to step 6:
86 goes into 652 7 times with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 5997.0
Deduct 602 from 652 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
86 goes into 500 5 times with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 5997.5
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
If we divide 700 by 86, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 5997.58
The remainder is 12 after subtracting 688 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
86 can be fit into 120 1 times, resulting in a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 5997.581
Subtract 86 from 120 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
86 goes into 340 3 times with a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 5997.5813
Subtract 258 from 340 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 11:
If we divide 820 by 86, we get 9 and a remainder of 46.
The next digit of our result is 9. 
Result so far: 5997.58139
Deduct 774 from 820 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
When dividing 460 by 86, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 5997.581395
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
86 goes into 300 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 5997.5813953
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
420 divided by 86 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 5997.58139534
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 5997.58139534 with a remaining 7.6e-08.
