We look at the division of 102303 by 4 
The aim is to understand the frequency of 4 in 102303.

Let's proceed to step 1:
4 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 4

Let's proceed to step 2:
If we divide 10 by 4, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 8 from 10, we get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 4

Moving on to step 3:
22 divided by 4 is 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 20 from 22 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 4

On to step 4:
The number 4 fits into 23 5 times, leaving a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 255.0
If we subtract 20 from 23, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 4

On to step 5:
4 can be fit into 30 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 2557.0
If we subtract 28 from 30, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 4

Moving on to step 6:
The number 4 fits into 23 5 times, leaving a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 25575.0
Subtract 20 from 23 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 25575.7
Subtracting 28 from 30 leaves us 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 8:
20 divided by 4 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 25575.75
Deduct 20 from 20 and we're left 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 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25575.75
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 10:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25575.75
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.

After the division, we end up with 25575.75 and a remainder of 0.0.
