We look at the division of 13445 by 27 
The aim is to understand the frequency of 27 in 13445.

On to step 1:
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: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 27

Moving on to step 2:
27 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 27

Let's proceed to step 3:
27 goes into 134 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 26 after subtracting 108 from 134.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 27

Going ahead to step 4:
The number 27 fits into 264 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 49.0
Subtract 243 from 264 to get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 27

Moving on to step 5:
27 can be fit into 215 7 times, resulting in a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 497.0
Deduct 189 from 215 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 6:
When dividing 260 by 27, we get 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 497.9
Subtracting 243 from 260 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
27 goes into 170 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 497.96
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
The number 27 fits into 80 2 times, leaving a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 497.962
The remainder is 26 after subtracting 54 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
The number 27 fits into 260 9 times, leaving a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 497.9629
Subtract 243 from 260 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
27 can be fit into 170 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 497.96296
If we take 162 away from 170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
When dividing 80 by 27, we get 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 497.962962
If we subtract 54 from 80, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
260 divided by 27 is 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 497.9629629
Deduct 243 from 260 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
27 goes into 170 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 497.96296296
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 497.96296296 with a remainder of 8e-09.
