We look at the division of 360020 by 86 
The aim is to understand the frequency of 86 in 360020.

Let's proceed to step 1:
86 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 86

Step 2:
The number 86 fits into 36 0 times, leaving a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 86

On to step 3:
360 divided by 86 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 344 from 360, we get 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 86

Let's proceed to step 4:
86 goes into 160 1 times with a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we take 86 away from 160, we end up with 74.
Grab the next digit (2) from the dividend, add it to 74, then carry on: 742 / 86

Let's proceed to step 5:
When dividing 742 by 86, we get 8 with a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 418.0
If we subtract 688 from 742, we get 54.
Append the next digit (0) from the dividend to 54 and continue with: 540 / 86

Moving on to step 6:
If we divide 540 by 86, we get 6 and a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 4186.0
If we take 516 away from 540, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
The number 86 fits into 240 2 times, leaving a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 4186.2
Subtract 172 from 240 to get 68.
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 goes into 680 7 times with a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 4186.27
Deduct 602 from 680 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
86 goes into 780 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 4186.279
If we take 774 away from 780, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
60 divided by 86 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 4186.279
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
If we divide 600 by 86, we get 6 and a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 4186.27906
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.

Advancing to step 12:
When dividing 840 by 86, we get 9 with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 4186.279069
Subtract 774 from 840 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 13:
660 divided by 86 is 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 4186.2790697
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.
Record the quotient 6 as the next digit in the result. 
Result so far: 4186.27906976
If we take 516 away from 580, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 4186.27906976 and a remainder of 6.4e-08.
