We look at the division of 460601 by 86 
The aim is to understand the frequency of 86 in 460601.

On to step 1:
If we divide 4 by 86, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 86

Advancing to step 2:
86 goes into 46 0 times with a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 46, we get 46.
Grab the next digit (0) from the dividend, add it to 46, then carry on: 460 / 86

Moving on to step 3:
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: 5.0
Subtracting 430 from 460 leaves us with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 86

Advancing to step 4:
86 goes into 306 3 times with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 53.0
If we subtract 258 from 306, we get 48.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 86

On to step 5:
86 goes into 480 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 535.0
If we take 430 away from 480, we end up with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 86

Advancing to step 6:
The number 86 fits into 501 5 times, leaving a remainder of 71.
The number 5 becomes the next digit in our result. 
Result so far: 5355.0
If we subtract 430 from 501, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 7:
86 can be fit into 710 8 times, resulting in a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 5355.8
Subtracting 688 from 710 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
If we divide 220 by 86, we get 2 and a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 5355.82
If we subtract 172 from 220, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
The number 86 fits into 480 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 5355.825
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
If we divide 500 by 86, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 5355.8255
Subtract 430 from 500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 5355.8255 with a remainder of 0.0007.
