459220 ÷ 72 
The aim is to understand the frequency of 72 in 459220.

On to step 1:
4 divided by 72 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 72

Advancing to step 2:
72 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 72

On to step 3:
72 can be fit into 459 6 times, resulting in a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 432 from 459, we get 27.
Include the next digit (2) from the dividend after 27, then repeat: 272 / 72

On to step 4:
72 can be fit into 272 3 times, resulting in a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we take 216 away from 272, we end up with 56.
Take the next digit (2) from the dividend and append it to 56, then repeat: 562 / 72

Step 5:
When dividing 562 by 72, we get 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 637.0
If we take 504 away from 562, we end up with 58.
Bring next digit (0) of the dividend behind the 58 and repeat the process: 580 / 72

Moving on to step 6:
72 can be fit into 580 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 6378.0
The remainder is 4 after subtracting 576 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
The number 72 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 6378.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
The number 72 fits into 400 5 times, leaving a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 6378.05
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 72, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 6378.055
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 6378.055, and the remainder is 0.004.
