We look at the division of 346455 by 27 
The aim is to understand the frequency of 27 in 346455.

On to step 1:
27 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 27

Step 2:
If we divide 34 by 27, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 27 from 34 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 27

On to step 3:
27 goes into 76 2 times with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 54 from 76, we get 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 27

Moving on to step 4:
224 divided by 27 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 128.0
The remainder is 8 after subtracting 216 from 224.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 27

Step 5:
The number 27 fits into 85 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 1283.0
Subtract 81 from 85 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 27

On to step 6:
When dividing 45 by 27, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 12831.0
Deduct 27 from 45 and we're left 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.

Advancing to step 7:
180 divided by 27 is 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 12831.6
The remainder is 18 after subtracting 162 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
27 goes into 180 6 times with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 12831.66
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.

After the division, we end up with 12831.66 and a remainder of 0.018.
