We divide 169872 by 27
The aim is to understand the frequency of 27 in 169872.

Advancing to step 1:
27 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 27

Moving on to step 2:
The number 27 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 27

Let's proceed to step 3:
The number 27 fits into 169 6 times, leaving a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 162 from 169, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 27

Going ahead to step 4:
If we divide 78 by 27, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 62.0
Subtracting 54 from 78 leaves us with 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 27

On to step 5:
27 goes into 247 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 629.0
Subtract 243 from 247 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 27

Step 6:
27 can be fit into 42 1 times, resulting in a remainder of 15.
The next digit of our result is 1. 
Result so far: 6291.0
If we take 27 away from 42, 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.

Step 7:
If we divide 150 by 27, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 6291.5
Subtracting 135 from 150 leaves us 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.

Advancing to step 8:
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: 6291.55
Subtract 135 from 150 to 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.

The final result is 6291.55 with a remainder of 0.015.
