We look at the division of 470243 by 86 
The aim is to understand the frequency of 86 in 470243.

On to step 1:
86 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 86

Going ahead to step 2:
47 divided by 86 is 0 with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 47 leaves us with 47.
Append the next digit (0) from the dividend to 47 and continue with: 470 / 86

Moving on to step 3:
470 divided by 86 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 430 from 470 to get 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 86

Going ahead to step 4:
86 can be fit into 402 4 times, resulting in a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 54.0
The remainder is 58 after subtracting 344 from 402.
Grab the next digit (4) from the dividend, add it to 58, then carry on: 584 / 86

Advancing to step 5:
86 goes into 584 6 times with a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 546.0
The remainder is 68 after subtracting 516 from 584.
Append the next digit (3) from the dividend to 68 and continue with: 683 / 86

Advancing to step 6:
86 can be fit into 683 7 times, resulting in a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 5467.0
Subtracting 602 from 683 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 7:
86 goes into 810 9 times with a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 5467.9
If we subtract 774 from 810, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
When dividing 360 by 86, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 5467.94
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
If we divide 160 by 86, we get 1 and a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 5467.941
Subtract 86 from 160 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 10:
When dividing 740 by 86, we get 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 5467.9418
If we take 688 away from 740, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
When dividing 520 by 86, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 5467.94186
If we take 516 away from 520, we end up 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.

Step 12:
86 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 5467.94186
If we subtract 0 from 40, we 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 13:
The number 86 fits into 400 4 times, leaving a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 5467.9418604
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
86 can be fit into 560 6 times, resulting in a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 5467.94186046
Subtract 516 from 560 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 5467.94186046 and a remainder of 4.4e-08.
