We divide 80678661 by 27
The aim is to understand the frequency of 27 in 80678661.

Let's proceed to step 1:
If we divide 8 by 27, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 27

On to step 2:
If we divide 80 by 27, we get 2 and a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 54 from 80 to get 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 27

Going ahead to step 3:
27 goes into 266 9 times with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 29.0
Deduct 243 from 266 and we're left with 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 27

Let's proceed to step 4:
If we divide 237 by 27, we get 8 and a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 298.0
If we subtract 216 from 237, we get 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 27

Moving on to step 5:
27 goes into 218 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 2988.0
Deduct 216 from 218 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 27

Step 6:
27 goes into 26 0 times with a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 29880.0
Deduct 0 from 26 and we're left with 26.
Fetch the next digit (6) from the dividend, attach it to 26 and continue: 266 / 27

Advancing to step 7:
27 goes into 266 9 times with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 298809.0
Subtracting 243 from 266 leaves us with 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 27

On to step 8:
If we divide 231 by 27, we get 8 and a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 2988098.0
If we subtract 216 from 231, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
The number 27 fits into 150 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2988098.5
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
The number 27 fits into 150 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 2988098.55
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 2988098.55 with a remaining 0.015.
