We're dividing 947658 by 86 
The aim is to understand the frequency of 86 in 947658.

Advancing to step 1:
When dividing 9 by 86, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 86

On to step 2:
If we divide 94 by 86, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 86 from 94 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 86

Advancing to step 3:
86 goes into 87 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 86 from 87 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 86

Let's proceed to step 4:
16 divided by 86 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 110.0
Subtract 0 from 16 to get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 86

Advancing to step 5:
86 can be fit into 165 1 times, resulting in a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 1101.0
Subtracting 86 from 165 leaves us with 79.
Take the next digit (8) from the dividend and append it to 79, then repeat: 798 / 86

Advancing to step 6:
86 can be fit into 798 9 times, resulting in a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 11019.0
The remainder is 24 after subtracting 774 from 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
86 goes into 240 2 times with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 11019.2
The remainder is 68 after subtracting 172 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
86 can be fit into 680 7 times, resulting in a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 11019.27
The remainder is 78 after subtracting 602 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
When dividing 780 by 86, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 11019.279
If we subtract 774 from 780, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
86 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 11019.279
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
600 divided by 86 is 6 with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 11019.27906
If we subtract 516 from 600, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 12:
86 can be fit into 840 9 times, resulting in a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 11019.279069
If we take 774 away from 840, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 13:
86 goes into 660 7 times with a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 11019.2790697
Subtract 602 from 660 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 14:
The number 86 fits into 580 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 11019.27906976
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 11019.27906976 with a remainder of 6.4e-08.
