We divide 213858 by 27
The aim is to understand the frequency of 27 in 213858.

On to step 1:
When dividing 2 by 27, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 27

Step 2:
If we divide 21 by 27, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 27

On to step 3:
213 divided by 27 is 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 189 from 213 leaves us with 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 27

Step 4:
27 can be fit into 248 9 times, resulting in a remainder of 5.
The next digit of our result is 9. 
Result so far: 79.0
Deduct 243 from 248 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 27

Let's proceed to step 5:
If we divide 55 by 27, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 792.0
If we take 54 away from 55, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 27

Let's proceed to step 6:
When dividing 18 by 27, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 7920.0
The remainder is 18 after subtracting 0 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
27 can be fit into 180 6 times, resulting in a remainder of 18.
The next digit of our result is 6. 
Result so far: 7920.6
If we take 162 away from 180, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
27 goes into 180 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 7920.66
Subtracting 162 from 180 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 7920.66 with a remainder of 0.018.
