We look at the division of 18713810 by 27 
The aim is to understand the frequency of 27 in 18713810.

Advancing to step 1:
1 divided by 27 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 27

Advancing to step 2:
When dividing 18 by 27, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 27

Let's proceed to step 3:
187 divided by 27 is 6 with a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 162 from 187 leaves us with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 27

Let's proceed to step 4:
When dividing 251 by 27, we get 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 69.0
If we subtract 243 from 251, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 27

Step 5:
When dividing 83 by 27, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 693.0
The remainder is 2 after subtracting 81 from 83.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 27

Advancing to step 6:
27 can be fit into 28 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 6931.0
Deduct 27 from 28 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 27

Step 7:
When dividing 11 by 27, we get 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 69310.0
Subtracting 0 from 11 leaves us with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 27

Step 8:
27 can be fit into 110 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 693104.0
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
20 divided by 27 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 693104.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
200 divided by 27 is 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 693104.07
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
27 can be fit into 110 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 693104.074
If we take 108 away from 110, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
27 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 693104.074
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
200 divided by 27 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 693104.07407
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
110 divided by 27 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 693104.074074
Subtracting 108 from 110 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 15:
27 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 693104.074074
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 16:
200 divided by 27 is 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 693104.07407407
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 693104.07407407 with a remainder of 1.1e-08.
