206521 ÷ 27 
The aim is to understand the frequency of 27 in 206521.

Advancing to step 1:
27 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 27

Going ahead to step 2:
When dividing 20 by 27, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 27

Advancing to step 3:
The number 27 fits into 206 7 times, leaving a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 189 from 206 leaves us with 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 27

On to step 4:
When dividing 175 by 27, we get 6 with a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Deduct 162 from 175 and we're left with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 27

Going ahead to step 5:
132 divided by 27 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 764.0
Subtract 108 from 132 to get 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 27

Step 6:
If we divide 241 by 27, we get 8 and a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 7648.0
If we take 216 away from 241, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
The number 27 fits into 250 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 7648.9
If we subtract 243 from 250, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
27 can be fit into 70 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 7648.92
Subtracting 54 from 70 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
27 goes into 160 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 7648.925
Deduct 135 from 160 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
The number 27 fits into 250 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 7648.9259
Deduct 243 from 250 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
27 goes into 70 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 7648.92592
The remainder is 16 after subtracting 54 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
27 can be fit into 160 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 7648.925925
Subtracting 135 from 160 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 13:
The number 27 fits into 250 9 times, leaving a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 7648.9259259
The remainder is 7 after subtracting 243 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 14:
If we divide 70 by 27, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 7648.92592592
If we take 54 away from 70, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 7648.92592592, with a leftover of 1.6e-08.
