We look at the division of 389606 by 27 
The aim is to understand the frequency of 27 in 389606.

Step 1:
If we divide 3 by 27, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 27

Let's proceed to step 2:
If we divide 38 by 27, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 27 away from 38, we end up with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 27

Step 3:
If we divide 119 by 27, we get 4 and a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 108 from 119 to get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 27

Step 4:
27 can be fit into 116 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 144.0
If we subtract 108 from 116, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 27

Going ahead to step 5:
27 goes into 80 2 times with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 1442.0
The remainder is 26 after subtracting 54 from 80.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 27

Let's proceed to step 6:
The number 27 fits into 266 9 times, leaving a remainder of 23.
The next digit of our result is 9. 
Result so far: 14429.0
If we subtract 243 from 266, we get 23.
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.
Use 8 as the next digit of our solution. 
Result so far: 14429.8
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.

Moving on to 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: 14429.85
If we take 135 away from 140, we end up 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.

Going ahead to step 9:
When dividing 50 by 27, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 14429.851
If we subtract 27 from 50, we get 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:
27 can be fit into 230 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 14429.8518
Subtracting 216 from 230 leaves us 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.

On to step 11:
27 goes into 140 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 14429.85185
Subtract 135 from 140 to 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.

Advancing to step 12:
The number 27 fits into 50 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 14429.851851
Subtracting 27 from 50 leaves us 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 13:
27 goes into 230 8 times with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 14429.8518518
Deduct 216 from 230 and we're left 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 14:
If we divide 140 by 27, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 14429.85185185
If we take 135 away from 140, we end up 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.

The final outcome is 14429.85185185, with a leftover of 5e-09.
