We look at the division of 968312 by 86 
The aim is to understand the frequency of 86 in 968312.

Going ahead to step 1:
86 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 86

On to step 2:
96 divided by 86 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 86 away from 96, we end up with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 86

On to step 3:
The number 86 fits into 108 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 86 from 108 to get 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 86

Step 4:
If we divide 223 by 86, we get 2 and a remainder of 51.
Write down 2 as next digit of the result. 
Result so far: 112.0
Subtracting 172 from 223 leaves us with 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 86

Let's proceed to step 5:
The number 86 fits into 511 5 times, leaving a remainder of 81.
Put 5 as the next digit of the answer. 
Result so far: 1125.0
Deduct 430 from 511 and we're left with 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 86

Step 6:
86 can be fit into 812 9 times, resulting in a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 11259.0
If we subtract 774 from 812, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 11259.4
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
360 divided by 86 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 11259.44
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 11259.44 and a remainder of 0.016.
