We divide 158941 by 86
The aim is to understand the frequency of 86 in 158941.

Step 1:
When dividing 1 by 86, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 86

Advancing to step 2:
When dividing 15 by 86, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 86

Moving on to step 3:
If we divide 158 by 86, we get 1 and a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 72 after subtracting 86 from 158.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 86

On to step 4:
729 divided by 86 is 8 with a remainder of 41.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 688 from 729 and we're left with 41.
Include the next digit (4) from the dividend after 41, then repeat: 414 / 86

Moving on to step 5:
414 divided by 86 is 4 with a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 184.0
The remainder is 70 after subtracting 344 from 414.
Include the next digit (1) from the dividend after 70, then repeat: 701 / 86

Advancing to step 6:
When dividing 701 by 86, we get 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 1848.0
If we take 688 away from 701, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
When dividing 130 by 86, we get 1 with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 1848.1
Subtracting 86 from 130 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
86 goes into 440 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 1848.15
If we take 430 away from 440, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 86 fits into 100 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1848.151
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 1848.1511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 1848.1511 with a remaining 0.00054.
