27696604 ÷ 18 
The aim is to understand the frequency of 18 in 27696604.

Going ahead to step 1:
The number 18 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 18

Moving on to step 2:
If we divide 27 by 18, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 18 away from 27, we end up with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 18

On to step 3:
18 can be fit into 96 5 times, resulting in a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 90 from 96 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 18

Moving on to step 4:
When dividing 69 by 18, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 153.0
Deduct 54 from 69 and we're left with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 18

Step 5:
156 divided by 18 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1538.0
If we subtract 144 from 156, we get 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 18

Let's proceed to step 6:
The number 18 fits into 126 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 15387.0
Subtract 126 from 126 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 18

Step 7:
When dividing 0 by 18, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 153870.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 18

Advancing to step 8:
If we divide 4 by 18, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 1538700.0
Subtracting 0 from 4 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 18 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1538700.2
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
When dividing 40 by 18, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1538700.22
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 1538700.22 with a remaining 0.004.
