We look at the division of 720248 by 4 
The aim is to understand the frequency of 4 in 720248.

Advancing to step 1:
If we divide 7 by 4, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 4 from 7 to get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 4

Step 2:
If we divide 32 by 4, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 0 after subtracting 32 from 32.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 4

Moving on to step 3:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 180.0
If we subtract 0 from 0, we get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 4

On to step 4:
4 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 1800.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 4

Advancing to step 5:
24 divided by 4 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 18006.0
The remainder is 0 after subtracting 24 from 24.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 4

Going ahead to step 6:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 180062.0
Subtracting 8 from 8 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 180062.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 180062.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 180062.0 with a remainder of 0.0.
