We look at the division of 336775 by 86 
The aim is to understand the frequency of 86 in 336775.

Let's proceed to step 1:
The number 86 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 86

Moving on to step 2:
The number 86 fits into 33 0 times, leaving a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 86

Going ahead to step 3:
86 can be fit into 336 3 times, resulting in a remainder of 78.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 258 from 336 leaves us with 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 86

Going ahead to step 4:
When dividing 787 by 86, we get 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtracting 774 from 787 leaves us with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 86

Going ahead to step 5:
137 divided by 86 is 1 with a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 391.0
The remainder is 51 after subtracting 86 from 137.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 86

Step 6:
515 divided by 86 is 5 with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 3915.0
The remainder is 85 after subtracting 430 from 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 7:
When dividing 850 by 86, we get 9 with a remainder of 76.
The number 9 becomes the next digit in our result. 
Result so far: 3915.9
Subtract 774 from 850 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 8:
When dividing 760 by 86, we get 8 with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 3915.98
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 9:
86 goes into 720 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 3915.988
Subtracting 688 from 720 leaves us 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.

The quotient of the division is 3915.988, and the remainder is 0.0032.
