253294 divided by 86 
The aim is to understand the frequency of 86 in 253294.

Advancing to step 1:
2 divided by 86 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 86

Advancing to step 2:
86 goes into 25 0 times with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 86

Step 3:
When dividing 253 by 86, we get 2 with a remainder of 81.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 172 from 253 and we're left with 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 86

Step 4:
812 divided by 86 is 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 29.0
The remainder is 38 after subtracting 774 from 812.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 86

On to step 5:
The number 86 fits into 389 4 times, leaving a remainder of 45.
The next digit of our result is 4. 
Result so far: 294.0
If we subtract 344 from 389, we get 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 86

Advancing to step 6:
The number 86 fits into 454 5 times, leaving a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 2945.0
If we subtract 430 from 454, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
240 divided by 86 is 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 2945.2
The remainder is 68 after subtracting 172 from 240.
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 8:
If we divide 680 by 86, we get 7 and a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 2945.27
Deduct 602 from 680 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
When dividing 780 by 86, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 2945.279
Subtracting 774 from 780 leaves us 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.

Going ahead to step 10:
60 divided by 86 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 2945.279
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
86 can be fit into 600 6 times, resulting in a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 2945.27906
Deduct 516 from 600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
840 divided by 86 is 9 with a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 2945.279069
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
86 can be fit into 660 7 times, resulting in a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 2945.2790697
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.

Let's proceed to step 14:
580 divided by 86 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 2945.27906976
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 2945.27906976 with a balance of 6.4e-08.
