We look at the division of 579708 by 86 
The aim is to understand the frequency of 86 in 579708.

Step 1:
5 divided by 86 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 86

Going ahead to step 2:
86 can be fit into 57 0 times, resulting in a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Take the next digit (9) from the dividend and append it to 57, then repeat: 579 / 86

Advancing to step 3:
When dividing 579 by 86, we get 6 with a remainder of 63.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 516 away from 579, we end up with 63.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 86

On to step 4:
86 can be fit into 637 7 times, resulting in a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 67.0
Deduct 602 from 637 and we're left with 35.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 86

Step 5:
The number 86 fits into 350 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 674.0
Subtracting 344 from 350 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 86

Going ahead to step 6:
68 divided by 86 is 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 6740.0
If we take 0 away from 68, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
The number 86 fits into 680 7 times, leaving a remainder of 78.
The next digit of our result is 7. 
Result so far: 6740.7
Deduct 602 from 680 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 8:
780 divided by 86 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 6740.79
Subtract 774 from 780 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
The number 86 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 6740.79
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
600 divided by 86 is 6 with a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 6740.7906
Subtract 516 from 600 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 11:
If we divide 840 by 86, we get 9 and a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 6740.79069
Deduct 774 from 840 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 12:
86 can be fit into 660 7 times, resulting in a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 6740.790697
If we subtract 602 from 660, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
86 goes into 580 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 6740.7906976
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
The number 86 fits into 640 7 times, leaving a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 6740.79069767
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 6740.79069767, and the remainder is 3.8e-08.
