We're dividing 881421 by 27 
The aim is to understand the frequency of 27 in 881421.

Step 1:
The number 27 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 27

Advancing to step 2:
88 divided by 27 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 81 away from 88, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 27

Going ahead to step 3:
71 divided by 27 is 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we take 54 away from 71, we end up with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 27

Step 4:
174 divided by 27 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 326.0
If we take 162 away from 174, we end up with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 27

Let's proceed to step 5:
122 divided by 27 is 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 3264.0
If we subtract 108 from 122, we get 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 27

On to step 6:
When dividing 141 by 27, we get 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 32645.0
If we take 135 away from 141, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
The number 27 fits into 60 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 32645.2
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
27 goes into 60 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 32645.22
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 32645.22 and a remainder of 0.006.
