We look at the division of 354182 by 86 
The aim is to understand the frequency of 86 in 354182.

Moving on to step 1:
86 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 86

On to step 2:
86 can be fit into 35 0 times, resulting in a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 86

Advancing to step 3:
If we divide 354 by 86, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 344 away from 354, we end up with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 86

Step 4:
The number 86 fits into 101 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 86 from 101 leaves us with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 86

Moving on to step 5:
86 can be fit into 158 1 times, resulting in a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 411.0
Deduct 86 from 158 and we're left with 72.
Take the next digit (2) from the dividend and append it to 72, then repeat: 722 / 86

On to step 6:
If we divide 722 by 86, we get 8 and a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 4118.0
Deduct 688 from 722 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
340 divided by 86 is 3 with a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 4118.3
Subtract 258 from 340 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 8:
86 can be fit into 820 9 times, resulting in a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 4118.39
If we take 774 away from 820, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
86 goes into 460 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 4118.395
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
86 goes into 300 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 4118.3953
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
420 divided by 86 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 4118.39534
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
86 can be fit into 760 8 times, resulting in a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 4118.395348
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 13:
720 divided by 86 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 4118.3953488
If we subtract 688 from 720, 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.

The final result is 4118.3953488 with a remainder of 3.2e-07.
