558318 divided by 27 
The aim is to understand the frequency of 27 in 558318.

Advancing to step 1:
27 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 27

Moving on to step 2:
27 goes into 55 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 54 from 55 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 27

Advancing to step 3:
27 can be fit into 18 0 times, resulting in a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 27

Let's proceed to step 4:
27 can be fit into 183 6 times, resulting in a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 206.0
The remainder is 21 after subtracting 162 from 183.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 27

On to step 5:
The number 27 fits into 211 7 times, leaving a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 2067.0
Subtracting 189 from 211 leaves us with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 27

Step 6:
The number 27 fits into 228 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 20678.0
If we take 216 away from 228, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
If we divide 120 by 27, we get 4 and a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 20678.4
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
If we divide 120 by 27, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 20678.44
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 20678.44 with a remainder of 0.012.
