We divide 573922 by 4
The aim is to understand the frequency of 4 in 573922.

Step 1:
5 divided by 4 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 4 from 5, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 4

Let's proceed to step 2:
The number 4 fits into 17 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 1 after subtracting 16 from 17.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 4

Step 3:
13 divided by 4 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
If we take 12 away from 13, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 4

Moving on to step 4:
19 divided by 4 is 4 with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 1434.0
Subtract 16 from 19 to get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 4

Step 5:
32 divided by 4 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 14348.0
If we take 32 away from 32, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 4

Advancing to step 6:
4 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 143480.0
Deduct 0 from 2 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 143480.5
The remainder is 0 after subtracting 20 from 20.
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 8:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 143480.5
Subtracting 0 from 0 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.

Moving on to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 143480.5
The remainder is 0 after subtracting 0 from 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 143480.5 with a remainder of 0.0.
