We're dividing 879296 by 86 
The aim is to understand the frequency of 86 in 879296.

Step 1:
86 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 86

Advancing to step 2:
86 can be fit into 87 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 1 after subtracting 86 from 87.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 86

Going ahead to step 3:
When dividing 19 by 86, we get 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 86

On to step 4:
When dividing 192 by 86, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Subtract 172 from 192 to get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 86

Advancing to step 5:
If we divide 209 by 86, we get 2 and a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 1022.0
Subtracting 172 from 209 leaves us with 37.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 86

Step 6:
376 divided by 86 is 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 10224.0
If we subtract 344 from 376, we 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.

Going ahead to step 7:
The number 86 fits into 320 3 times, leaving a remainder of 62.
The next digit of our result is 3. 
Result so far: 10224.3
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.

Going ahead to step 8:
When dividing 620 by 86, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 10224.37
Subtracting 602 from 620 leaves us with 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.
Record the quotient 2 as the next digit in the result. 
Result so far: 10224.372
Subtract 172 from 180 to get 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:
If we divide 80 by 86, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 10224.372
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:
If we divide 800 by 86, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 10224.37209
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.

Moving on to step 12:
260 divided by 86 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 10224.372093
Subtract 258 from 260 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10224.372093
If we take 0 away from 20, we end up with 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:
If we divide 200 by 86, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 10224.37209302
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 10224.37209302, with a leftover of 2.8e-08.
