2150 ÷ 27 
The aim is to understand the frequency of 27 in 2150.

Step 1:
27 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 27

On to step 2:
When dividing 21 by 27, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 27

Moving on to step 3:
If we divide 215 by 27, we get 7 and a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 189 from 215, we get 26.
Bring next digit (0) of the dividend behind the 26 and repeat the process: 260 / 27

Advancing to step 4:
27 goes into 260 9 times with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtract 243 from 260 to 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.

Advancing to step 5:
If we divide 170 by 27, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 79.6
Deduct 162 from 170 and we're left 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.

Step 6:
When dividing 80 by 27, we get 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 79.62
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.

Let's proceed to step 7:
27 goes into 260 9 times with a remainder of 17.
The next digit of our result is 9. 
Result so far: 79.629
Subtract 243 from 260 to 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.

Advancing to step 8:
170 divided by 27 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 79.6296
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
27 can be fit into 80 2 times, resulting in a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 79.62962
If we subtract 54 from 80, we 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.

Moving on to 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: 79.629629
If we take 243 away from 260, we end up 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.

Advancing to step 11:
When dividing 170 by 27, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 79.6296296
Subtract 162 from 170 to 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.

Let's proceed to step 12:
80 divided by 27 is 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 79.62962962
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.

Our division results in 79.62962962 with a remaining 2.6e-08.
