We look at the division of 410954 by 86 
The aim is to understand the frequency of 86 in 410954.

On to step 1:
The number 86 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 86

Advancing to step 2:
86 goes into 41 0 times with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 86

Moving on to step 3:
86 can be fit into 410 4 times, resulting in a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 344 from 410 and we're left with 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 86

Step 4:
When dividing 669 by 86, we get 7 with a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we subtract 602 from 669, we get 67.
Include the next digit (5) from the dividend after 67, then repeat: 675 / 86

Going ahead to step 5:
86 goes into 675 7 times with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 477.0
Subtract 602 from 675 to get 73.
Include the next digit (4) from the dividend after 73, then repeat: 734 / 86

Step 6:
If we divide 734 by 86, we get 8 and a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 4778.0
If we take 688 away from 734, 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.

On to step 7:
When dividing 460 by 86, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 4778.5
If we subtract 430 from 460, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
86 can be fit into 300 3 times, resulting in a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 4778.53
Subtracting 258 from 300 leaves us 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.

Let's proceed to step 9:
420 divided by 86 is 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 4778.534
If we take 344 away from 420, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
When dividing 760 by 86, we get 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 4778.5348
Subtracting 688 from 760 leaves us 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 11:
720 divided by 86 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 4778.53488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 4778.53488 and a remainder of 3.2e-05.
