We divide 403949 by 27
The aim is to understand the frequency of 27 in 403949.

Moving on to step 1:
If we divide 4 by 27, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 27

Let's proceed to step 2:
40 divided by 27 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 27 from 40, we get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 27

Advancing to step 3:
The number 27 fits into 133 4 times, leaving a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 108 from 133 leaves us with 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 27

Going ahead to step 4:
If we divide 259 by 27, we get 9 and a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
Subtracting 243 from 259 leaves us with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 27

Going ahead to step 5:
The number 27 fits into 164 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 1496.0
Deduct 162 from 164 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 27

Let's proceed to step 6:
27 goes into 29 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 14961.0
If we subtract 27 from 29, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 27 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 14961.0
Subtracting 0 from 20 leaves us 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.

Let's proceed to step 8:
When dividing 200 by 27, we get 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 14961.07
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.

Advancing to step 9:
110 divided by 27 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 14961.074
If we subtract 108 from 110, we get 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 10:
If we divide 20 by 27, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 14961.074
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.

Step 11:
27 goes into 200 7 times with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 14961.07407
If we subtract 189 from 200, we 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 12:
27 can be fit into 110 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 14961.074074
Deduct 108 from 110 and we're left 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 13:
The number 27 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 14961.074074
Subtract 0 from 20 to 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.

Advancing to step 14:
27 goes into 200 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 14961.07407407
If we take 189 away from 200, we end up 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 14961.07407407 with a remainder of 1.1e-08.
