22902 ÷ 4 
The aim is to understand the frequency of 4 in 22902.

Step 1:
The number 4 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 4

Let's proceed to step 2:
4 can be fit into 22 5 times, resulting in a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 20 from 22 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 4

Advancing to step 3:
4 can be fit into 29 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we take 28 away from 29, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 4

Let's proceed to step 4:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 572.0
The remainder is 2 after subtracting 8 from 10.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 4

Step 5:
If we divide 22 by 4, we get 5 and a remainder of 2.
The next digit of our result is 5. 
Result so far: 5725.0
Subtract 20 from 22 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 6:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5725.5
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.

Going ahead to step 7:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5725.5
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.

Step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5725.5
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.

The final result is 5725.5 with a remainder of 0.0.
