Let's divide 865331 by 86
The aim is to understand the frequency of 86 in 865331.

Advancing to step 1:
86 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 86

Let's proceed to step 2:
If we divide 86 by 86, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 86 away from 86, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 86

Let's proceed to step 3:
The number 86 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 5, we get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 86

Advancing to step 4:
86 goes into 53 0 times with a remainder of 53.
The next digit of our result is 0. 
Result so far: 100.0
Subtract 0 from 53 to get 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 86

Let's proceed to step 5:
If we divide 533 by 86, we get 6 and a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 1006.0
Subtract 516 from 533 to get 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 86

Let's proceed to step 6:
86 can be fit into 171 1 times, resulting in a remainder of 85.
Write down 1 as next digit of the result. 
Result so far: 10061.0
Subtracting 86 from 171 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 7:
If we divide 850 by 86, we get 9 and a remainder of 76.
Put 9 as the next digit of the answer. 
Result so far: 10061.9
If we subtract 774 from 850, we 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:
If we divide 760 by 86, we get 8 and a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 10061.98
Deduct 688 from 760 and we're left with 72.
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:
The number 86 fits into 720 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 10061.988
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.

Our division results in 10061.988 with a remaining 0.0032.
