96398439 divided by 27 
The aim is to understand the frequency of 27 in 96398439.

Going ahead to step 1:
27 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 27

Moving on to step 2:
The number 27 fits into 96 3 times, leaving a remainder of 15.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 15 after subtracting 81 from 96.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 27

Going ahead to step 3:
27 goes into 153 5 times with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
The remainder is 18 after subtracting 135 from 153.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 27

Going ahead to step 4:
When dividing 189 by 27, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 357.0
The remainder is 0 after subtracting 189 from 189.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 27

Step 5:
When dividing 8 by 27, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 3570.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 27

Step 6:
If we divide 84 by 27, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 35703.0
Deduct 81 from 84 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 27

Moving on to step 7:
33 divided by 27 is 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 357031.0
If we take 27 away from 33, we end up with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 27

Let's proceed to step 8:
The number 27 fits into 69 2 times, leaving a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 3570312.0
Deduct 54 from 69 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 27 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3570312.5
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
The number 27 fits into 150 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3570312.55
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 3570312.55 and a remainder of 0.015.
