We look at the division of 576322 by 72 
The aim is to understand the frequency of 72 in 576322.

Let's proceed to step 1:
5 divided by 72 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 72

Moving on to step 2:
57 divided by 72 is 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Bring next digit (6) of the dividend behind the 57 and repeat the process: 576 / 72

On to step 3:
576 divided by 72 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 576 from 576 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 72

Going ahead to step 4:
3 divided by 72 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 80.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 72

Let's proceed to step 5:
The number 72 fits into 32 0 times, leaving a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 800.0
Subtracting 0 from 32 leaves us with 32.
Grab the next digit (2) from the dividend, add it to 32, then carry on: 322 / 72

Advancing to step 6:
The number 72 fits into 322 4 times, leaving a remainder of 34.
The next digit of our result is 4. 
Result so far: 8004.0
Subtract 288 from 322 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
72 can be fit into 340 4 times, resulting in a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 8004.4
If we take 288 away from 340, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
When dividing 520 by 72, we get 7 with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 8004.47
If we subtract 504 from 520, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
72 can be fit into 160 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 8004.472
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
When dividing 160 by 72, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 8004.4722
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 8004.4722, and the remainder is 0.00016.
