665756 ÷ 72 
The aim is to understand the frequency of 72 in 665756.

Step 1:
72 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 72

Moving on to step 2:
When dividing 66 by 72, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 72

Moving on to step 3:
72 goes into 665 9 times with a remainder of 17.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 648 from 665 leaves us with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 72

Going ahead to step 4:
The number 72 fits into 177 2 times, leaving a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 92.0
The remainder is 33 after subtracting 144 from 177.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 72

Going ahead to step 5:
If we divide 335 by 72, we get 4 and a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 924.0
Subtract 288 from 335 to get 47.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 72

Let's proceed to step 6:
When dividing 476 by 72, we get 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 9246.0
If we take 432 away from 476, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
If we divide 440 by 72, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 9246.6
If we take 432 away from 440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
When dividing 80 by 72, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 9246.61
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 72 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 9246.611
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 9246.611 and a remainder of 0.0008.
