239916 divided by 72 
The aim is to understand the frequency of 72 in 239916.

Let's proceed to step 1:
If we divide 2 by 72, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 72

Moving on to step 2:
23 divided by 72 is 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 72

On to step 3:
72 goes into 239 3 times with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 216 from 239 to get 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 72

Let's proceed to step 4:
When dividing 239 by 72, we get 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtract 216 from 239 to get 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 72

Step 5:
If we divide 231 by 72, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 333.0
If we take 216 away from 231, we end up with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 72

Going ahead to step 6:
156 divided by 72 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 3332.0
Subtracting 144 from 156 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
If we divide 120 by 72, we get 1 and a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 3332.1
If we subtract 72 from 120, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
If we divide 480 by 72, we get 6 and a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 3332.16
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
72 goes into 480 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 3332.166
If we subtract 432 from 480, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 3332.166 with a remaining 0.0048.
