We look at the division of 52574 by 27 
The aim is to understand the frequency of 27 in 52574.

Going ahead to step 1:
When dividing 5 by 27, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 27

Step 2:
52 divided by 27 is 1 with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 27 from 52 leaves us with 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 27

Moving on to step 3:
The number 27 fits into 255 9 times, leaving a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 243 from 255 leaves us with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 27

Going ahead to step 4:
When dividing 127 by 27, we get 4 with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 194.0
If we take 108 away from 127, we end up with 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 27

Moving on to step 5:
When dividing 194 by 27, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 1947.0
Deduct 189 from 194 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 6:
When dividing 50 by 27, we get 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1947.1
The remainder is 23 after subtracting 27 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
27 can be fit into 230 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 1947.18
If we take 216 away from 230, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
140 divided by 27 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1947.185
If we subtract 135 from 140, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
50 divided by 27 is 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1947.1851
If we take 27 away from 50, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
The number 27 fits into 230 8 times, leaving a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 1947.18518
Subtract 216 from 230 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
If we divide 140 by 27, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 1947.185185
Deduct 135 from 140 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
27 can be fit into 50 1 times, resulting in a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1947.1851851
Deduct 27 from 50 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
When dividing 230 by 27, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 1947.18518518
If we subtract 216 from 230, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 1947.18518518, with a leftover of 1.4e-08.
