We look at the division of 118702 by 86 
The aim is to understand the frequency of 86 in 118702.

Going ahead to step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 86

Step 2:
86 can be fit into 11 0 times, resulting in a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 86

Advancing to step 3:
If we divide 118 by 86, we get 1 and a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 86 from 118 and we're left with 32.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 86

Step 4:
When dividing 327 by 86, we get 3 with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 258 from 327 leaves us with 69.
Grab the next digit (0) from the dividend, add it to 69, then carry on: 690 / 86

Advancing to step 5:
When dividing 690 by 86, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 138.0
Subtracting 688 from 690 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 86

Step 6:
The number 86 fits into 22 0 times, leaving a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 1380.0
If we take 0 away from 22, we end up 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.

Step 7:
If we divide 220 by 86, we get 2 and a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 1380.2
Subtracting 172 from 220 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
The number 86 fits into 480 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1380.25
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
If we divide 500 by 86, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1380.255
The remainder is 70 after subtracting 430 from 500.
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 outcome is 1380.255, with a leftover of 0.007.
