27129699 ÷ 27 
The aim is to understand the frequency of 27 in 27129699.

Advancing to step 1:
The number 27 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 27

Advancing to step 2:
27 can be fit into 27 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 27 from 27 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 27

Step 3:
27 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 27

On to step 4:
The number 27 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 100.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 27

Advancing to step 5:
27 can be fit into 129 4 times, resulting in a remainder of 21.
The next digit of our result is 4. 
Result so far: 1004.0
If we subtract 108 from 129, we get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 27

Going ahead to step 6:
If we divide 216 by 27, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 10048.0
Subtracting 216 from 216 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 27

On to step 7:
The number 27 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 100480.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 27

Advancing to step 8:
99 divided by 27 is 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 1004803.0
If we subtract 81 from 99, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
The number 27 fits into 180 6 times, leaving a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 1004803.6
If we subtract 162 from 180, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
27 goes into 180 6 times with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 1004803.66
The remainder is 18 after subtracting 162 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 1004803.66 and a remainder of 0.018.
