We look at the division of 799233 by 86 
The aim is to understand the frequency of 86 in 799233.

Step 1:
The number 86 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 86

Going ahead to step 2:
86 can be fit into 79 0 times, resulting in a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Take the next digit (9) from the dividend and append it to 79, then repeat: 799 / 86

Let's proceed to step 3:
86 can be fit into 799 9 times, resulting in a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 774 away from 799, we end up with 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 86

Advancing to step 4:
86 goes into 252 2 times with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 92.0
The remainder is 80 after subtracting 172 from 252.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 86

Step 5:
If we divide 803 by 86, we get 9 and a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 929.0
If we take 774 away from 803, we end up with 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 86

Moving on to step 6:
86 goes into 293 3 times with a remainder of 35.
The next digit of our result is 3. 
Result so far: 9293.0
Subtract 258 from 293 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
350 divided by 86 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 9293.4
The remainder is 6 after subtracting 344 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 86, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 9293.4
Subtracting 0 from 60 leaves us 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.

Step 9:
When dividing 600 by 86, we get 6 with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 9293.406
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.

On to step 10:
If we divide 840 by 86, we get 9 and a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 9293.4069
If we subtract 774 from 840, we 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 11:
When dividing 660 by 86, we get 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 9293.40697
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
The number 86 fits into 580 6 times, leaving a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 9293.406976
Subtracting 516 from 580 leaves us 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 13:
If we divide 640 by 86, we get 7 and a remainder of 38.
The next digit of our result is 7. 
Result so far: 9293.4069767
Subtract 602 from 640 to 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.

On to step 14:
380 divided by 86 is 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 9293.40697674
Subtracting 344 from 380 leaves us 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.

The final outcome is 9293.40697674, with a leftover of 3.6e-08.
