858472 divided by 72 
The aim is to understand the frequency of 72 in 858472.

Step 1:
72 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 72

Advancing to step 2:
The number 72 fits into 85 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 13 after subtracting 72 from 85.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 72

Step 3:
If we divide 138 by 72, we get 1 and a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 72 from 138 leaves us with 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 72

Moving on to step 4:
The number 72 fits into 664 9 times, leaving a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 119.0
Deduct 648 from 664 and we're left with 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 72

Step 5:
72 goes into 167 2 times with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 1192.0
The remainder is 23 after subtracting 144 from 167.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 72

Moving on to step 6:
72 can be fit into 232 3 times, resulting in a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 11923.0
The remainder is 16 after subtracting 216 from 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
The number 72 fits into 160 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 11923.2
Subtracting 144 from 160 leaves us 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.

Advancing to step 8:
The number 72 fits into 160 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 11923.22
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 11923.22 with a balance of 0.016.
