723390 ÷ 72 
The aim is to understand the frequency of 72 in 723390.

Step 1:
When dividing 7 by 72, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 72

On to step 2:
72 divided by 72 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 72 from 72, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 72

Step 3:
3 divided by 72 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 3, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 72

On to step 4:
The number 72 fits into 33 0 times, leaving a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtract 0 from 33 to get 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 72

Moving on to step 5:
If we divide 339 by 72, we get 4 and a remainder of 51.
The number 4 becomes the next digit in our result. 
Result so far: 1004.0
Subtracting 288 from 339 leaves us with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 72

Advancing to step 6:
When dividing 510 by 72, we get 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 10047.0
Deduct 504 from 510 and we're left 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.

Let's proceed to step 7:
60 divided by 72 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 10047.0
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.

Let's proceed to step 8:
72 can be fit into 600 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 10047.08
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.

Moving on to step 9:
If we divide 240 by 72, we get 3 and a remainder of 24.
The next digit of our result is 3. 
Result so far: 10047.083
Deduct 216 from 240 and we're left 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.

Going ahead to step 10:
240 divided by 72 is 3 with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 10047.0833
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 10047.0833 with a balance of 0.00024.
