681652 divided by 72 
The aim is to understand the frequency of 72 in 681652.

On to step 1:
When dividing 6 by 72, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 72

Advancing to step 2:
When dividing 68 by 72, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 72

Moving on to step 3:
72 can be fit into 681 9 times, resulting in a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 33 after subtracting 648 from 681.
Fetch the next digit (6) from the dividend, attach it to 33 and continue: 336 / 72

On to step 4:
The number 72 fits into 336 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we take 288 away from 336, we end up with 48.
Take the next digit (5) from the dividend and append it to 48, then repeat: 485 / 72

Advancing to step 5:
If we divide 485 by 72, we get 6 and a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 946.0
If we subtract 432 from 485, we get 53.
Bring next digit (2) of the dividend behind the 53 and repeat the process: 532 / 72

Advancing to step 6:
If we divide 532 by 72, we get 7 and a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 9467.0
Subtract 504 from 532 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
When dividing 280 by 72, we get 3 with a remainder of 64.
The next digit of our result is 3. 
Result so far: 9467.3
Subtract 216 from 280 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
72 goes into 640 8 times with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 9467.38
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
72 can be fit into 640 8 times, resulting in a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 9467.388
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 9467.388 with a remainder of 0.0064.
