We look at the division of 126316 by 86 
The aim is to understand the frequency of 86 in 126316.

Moving on to step 1:
86 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 86

Moving on to step 2:
86 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 86

Step 3:
The number 86 fits into 126 1 times, leaving a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 86 from 126 to get 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 86

Advancing to step 4:
86 can be fit into 403 4 times, resulting in a remainder of 59.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 59 after subtracting 344 from 403.
Fetch the next digit (1) from the dividend, attach it to 59 and continue: 591 / 86

Advancing to step 5:
The number 86 fits into 591 6 times, leaving a remainder of 75.
Put 6 as the next digit of the answer. 
Result so far: 146.0
Deduct 516 from 591 and we're left with 75.
Grab the next digit (6) from the dividend, add it to 75, then carry on: 756 / 86

Step 6:
756 divided by 86 is 8 with a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 1468.0
Subtracting 688 from 756 leaves us 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.

Let's proceed to step 7:
86 can be fit into 680 7 times, resulting in a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 1468.7
The remainder is 78 after subtracting 602 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 8:
If we divide 780 by 86, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 1468.79
If we take 774 away from 780, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
When dividing 60 by 86, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1468.79
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:
The number 86 fits into 600 6 times, leaving a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 1468.7906
If we subtract 516 from 600, we 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.

Moving on 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: 1468.79069
Subtract 774 from 840 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 12:
660 divided by 86 is 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 1468.790697
Subtract 602 from 660 to 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:
580 divided by 86 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 1468.7906976
If we take 516 away from 580, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
The number 86 fits into 640 7 times, leaving a remainder of 38.
The next digit of our result is 7. 
Result so far: 1468.79069767
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 1468.79069767 with a balance of 3.8e-08.
