163230 ÷ 72 
The aim is to understand the frequency of 72 in 163230.

Moving on to step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 72

Going ahead to step 2:
16 divided by 72 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 72

Let's proceed to step 3:
The number 72 fits into 163 2 times, leaving a remainder of 19.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 19 after subtracting 144 from 163.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 72

Moving on to step 4:
192 divided by 72 is 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 48 after subtracting 144 from 192.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 72

Moving on to step 5:
When dividing 483 by 72, we get 6 with a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 226.0
Subtract 432 from 483 to get 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 72

Step 6:
When dividing 510 by 72, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 2267.0
If we take 504 away from 510, 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.

Going ahead to step 7:
72 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 2267.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
72 goes into 600 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 2267.08
The remainder is 24 after subtracting 576 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
72 goes into 240 3 times with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 2267.083
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
72 goes into 240 3 times with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 2267.0833
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 2267.0833 with a remaining 0.00024.
