We look at the division of 16270 by 72 
The aim is to understand the frequency of 72 in 16270.

Advancing to step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 72

Advancing to step 2:
When dividing 16 by 72, we get 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 72

Moving on to step 3:
If we divide 162 by 72, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 144 from 162 to get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 72

Moving on to step 4:
The number 72 fits into 187 2 times, leaving a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 22.0
The remainder is 43 after subtracting 144 from 187.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 72

Step 5:
72 can be fit into 430 5 times, resulting in a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 225.0
If we take 360 away from 430, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 6:
The number 72 fits into 700 9 times, leaving a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 225.9
If we take 648 away from 700, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 7:
72 can be fit into 520 7 times, resulting in a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 225.97
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
When dividing 160 by 72, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 225.972
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 225.9722
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 225.9722 with a remaining 0.00016.
