We're dividing 28510 by 4 
The aim is to understand the frequency of 4 in 28510.

Step 1:
2 divided by 4 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 4

Let's proceed to step 2:
When dividing 28 by 4, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 28 from 28, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 4

Step 3:
If we divide 5 by 4, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 71.0
Deduct 4 from 5 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 4

Step 4:
The number 4 fits into 11 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 712.0
If we take 8 away from 11, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 4

Let's proceed to step 5:
4 goes into 30 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 7127.0
Subtract 28 from 30 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.

Moving 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: 7127.5
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 7:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7127.5
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.

On to step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7127.5
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 7127.5 with a remainder of 0.0.
