We're dividing 159447 by 86 
The aim is to understand the frequency of 86 in 159447.

Going ahead to step 1:
1 divided by 86 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 86

Let's proceed to step 2:
If we divide 15 by 86, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 86

Moving on to step 3:
86 goes into 159 1 times with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 86 from 159 leaves us with 73.
Fetch the next digit (4) from the dividend, attach it to 73 and continue: 734 / 86

Advancing to step 4:
86 goes into 734 8 times with a remainder of 46.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 688 from 734 leaves us with 46.
Fetch the next digit (4) from the dividend, attach it to 46 and continue: 464 / 86

Step 5:
86 can be fit into 464 5 times, resulting in a remainder of 34.
Use 5 as the next digit of our solution. 
Result so far: 185.0
The remainder is 34 after subtracting 430 from 464.
Append the next digit (7) from the dividend to 34 and continue with: 347 / 86

Advancing to step 6:
When dividing 347 by 86, we get 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 1854.0
Deduct 344 from 347 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
The number 86 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1854.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
86 can be fit into 300 3 times, resulting in a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 1854.03
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
86 goes into 420 4 times with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 1854.034
If we take 344 away from 420, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
760 divided by 86 is 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 1854.0348
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
720 divided by 86 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 1854.03488
Deduct 688 from 720 and we're left 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.

Our division results in 1854.03488 with a remaining 3.2e-05.
