936424 ÷ 72 
The aim is to understand the frequency of 72 in 936424.

Let's proceed to step 1:
When dividing 9 by 72, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 72

On to step 2:
72 can be fit into 93 1 times, resulting in a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 72 from 93, we get 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 72

Step 3:
216 divided by 72 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 216 away from 216, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 72

Going ahead to step 4:
72 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 130.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 72

Advancing to step 5:
72 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 1300.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 72

On to step 6:
The number 72 fits into 424 5 times, leaving a remainder of 64.
Record the quotient 5 as the next digit in the result. 
Result so far: 13005.0
The remainder is 64 after subtracting 360 from 424.
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 7:
When dividing 640 by 72, we get 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 13005.8
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.

Step 8:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 13005.88
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.

In conclusion, the division gives 13005.88 with a balance of 0.064.
