We're dividing 249232 by 86 
The aim is to understand the frequency of 86 in 249232.

Moving on to step 1:
86 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 86

Step 2:
The number 86 fits into 24 0 times, leaving a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 86

Step 3:
When dividing 249 by 86, we get 2 with a remainder of 77.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 172 from 249 leaves us with 77.
Append the next digit (2) from the dividend to 77 and continue with: 772 / 86

Going ahead to step 4:
The number 86 fits into 772 8 times, leaving a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we subtract 688 from 772, we get 84.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 86

Going ahead to step 5:
If we divide 843 by 86, we get 9 and a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 289.0
If we take 774 away from 843, we end up with 69.
Include the next digit (2) from the dividend after 69, then repeat: 692 / 86

Moving on to step 6:
86 can be fit into 692 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 2898.0
Subtracting 688 from 692 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
The number 86 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 2898.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
If we divide 400 by 86, we get 4 and a remainder of 56.
The next digit of our result is 4. 
Result so far: 2898.04
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
86 goes into 560 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 2898.046
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
When dividing 440 by 86, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 2898.0465
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
The number 86 fits into 100 1 times, leaving a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 2898.04651
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
If we divide 140 by 86, we get 1 and a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 2898.046511
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 2898.046511, with a leftover of 5.4e-06.
