Let's divide 331638 by 27
The aim is to understand the frequency of 27 in 331638.

Let's proceed to step 1:
When dividing 3 by 27, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 27

Let's proceed to step 2:
The number 27 fits into 33 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 27 away from 33, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 27

Going ahead to step 3:
When dividing 61 by 27, we get 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 54 from 61 and we're left with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 27

Let's proceed to step 4:
When dividing 76 by 27, we get 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 122.0
Subtract 54 from 76 to get 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 27

Advancing to step 5:
223 divided by 27 is 8 with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 1228.0
Subtracting 216 from 223 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 27

Let's proceed to step 6:
78 divided by 27 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 12282.0
If we take 54 away from 78, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
When dividing 240 by 27, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 12282.8
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
240 divided by 27 is 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 12282.88
Deduct 216 from 240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 12282.88 with a remaining 0.024.
