391013 divided by 27 
The aim is to understand the frequency of 27 in 391013.

Going ahead to step 1:
27 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 27

Moving on to step 2:
If we divide 39 by 27, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 27 from 39, we get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 27

Moving on to step 3:
121 divided by 27 is 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 108 away from 121, we end up with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 27

Let's proceed to step 4:
The number 27 fits into 130 4 times, leaving a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 144.0
If we subtract 108 from 130, we get 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 27

Step 5:
The number 27 fits into 221 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 1448.0
If we take 216 away from 221, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 27

On to step 6:
53 divided by 27 is 1 with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 14481.0
The remainder is 26 after subtracting 27 from 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
27 goes into 260 9 times with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 14481.9
If we subtract 243 from 260, we 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.

Going ahead to step 8:
The number 27 fits into 170 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 14481.96
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.

Moving on to step 9:
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: 14481.962
If we take 54 away from 80, we end up 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.

Step 10:
27 goes into 260 9 times with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 14481.9629
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.

On to step 11:
When dividing 170 by 27, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 14481.96296
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.

Moving on to step 12:
When dividing 80 by 27, we get 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 14481.962962
Subtract 54 from 80 to 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 13:
If we divide 260 by 27, we get 9 and a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 14481.9629629
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.

On to step 14:
When dividing 170 by 27, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 14481.96296296
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.

The final result is 14481.96296296 with a remainder of 8e-09.
