We look at the division of 326574 by 86 
The aim is to understand the frequency of 86 in 326574.

Advancing to step 1:
When dividing 3 by 86, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 86

Let's proceed to step 2:
32 divided by 86 is 0 with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 86

Going ahead to step 3:
86 can be fit into 326 3 times, resulting in a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 68 after subtracting 258 from 326.
Append the next digit (5) from the dividend to 68 and continue with: 685 / 86

Advancing to step 4:
86 can be fit into 685 7 times, resulting in a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 602 from 685 and we're left with 83.
Append the next digit (7) from the dividend to 83 and continue with: 837 / 86

Moving on to step 5:
86 can be fit into 837 9 times, resulting in a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 379.0
The remainder is 63 after subtracting 774 from 837.
Include the next digit (4) from the dividend after 63, then repeat: 634 / 86

Let's proceed to step 6:
86 can be fit into 634 7 times, resulting in a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 3797.0
Subtract 602 from 634 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
320 divided by 86 is 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 3797.3
If we subtract 258 from 320, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
The number 86 fits into 620 7 times, leaving a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 3797.37
If we subtract 602 from 620, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
If we divide 180 by 86, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 3797.372
Subtracting 172 from 180 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 86 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 3797.372
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
When dividing 800 by 86, we get 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 3797.37209
Deduct 774 from 800 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 12:
86 can be fit into 260 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 3797.372093
Subtracting 258 from 260 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
If we divide 20 by 86, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 3797.372093
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
200 divided by 86 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 3797.37209302
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 3797.37209302 and a remainder of 2.8e-08.
