We look at the division of 113291 by 86 
The aim is to understand the frequency of 86 in 113291.

Moving on to step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 86

Advancing to step 2:
11 divided by 86 is 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 86

Going ahead to step 3:
When dividing 113 by 86, we get 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 86 from 113 to get 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 86

Moving on to step 4:
When dividing 272 by 86, we get 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 258 from 272 and we're left with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 86

Moving on to step 5:
If we divide 149 by 86, we get 1 and a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
The remainder is 63 after subtracting 86 from 149.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 86

Advancing to step 6:
The number 86 fits into 631 7 times, leaving a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 1317.0
If we subtract 602 from 631, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
86 goes into 290 3 times with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 1317.3
If we take 258 away from 290, we end up 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.

Advancing to step 8:
86 goes into 320 3 times with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 1317.33
The remainder is 62 after subtracting 258 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 1317.33 with a remaining 0.062.
