Let's divide 816528 by 27
The aim is to understand the frequency of 27 in 816528.

Advancing to step 1:
When dividing 8 by 27, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 27

Advancing to step 2:
If we divide 81 by 27, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 81 away from 81, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 27

Moving on to step 3:
The number 27 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 27

Advancing to step 4:
65 divided by 27 is 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 302.0
If we subtract 54 from 65, we get 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 27

Let's proceed to step 5:
27 goes into 112 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 3024.0
Deduct 108 from 112 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 27

Going ahead to step 6:
27 can be fit into 48 1 times, resulting in a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 30241.0
The remainder is 21 after subtracting 27 from 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
The number 27 fits into 210 7 times, leaving a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 30241.7
If we subtract 189 from 210, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 8:
If we divide 210 by 27, we get 7 and a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 30241.77
If we take 189 away from 210, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 30241.77, with a leftover of 0.021.
