488245 divided by 4 
The aim is to understand the frequency of 4 in 488245.

On to step 1:
4 goes into 4 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 4 away from 4, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 4

Step 2:
4 goes into 8 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 8 from 8, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 4

Advancing to step 3:
4 goes into 8 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 4

Going ahead to step 4:
If we divide 2 by 4, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 1220.0
If we subtract 0 from 2, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 4

On to step 5:
4 goes into 24 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 12206.0
Deduct 24 from 24 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 4

Let's proceed to step 6:
4 goes into 5 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 122061.0
The remainder is 1 after subtracting 4 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
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: 122061.2
Subtract 8 from 10 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.

Advancing to step 8:
4 goes into 20 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 122061.25
Subtracting 20 from 20 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 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 122061.25
Subtract 0 from 0 to 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.

Going ahead to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 122061.25
Deduct 0 from 0 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.

The final outcome is 122061.25, with a leftover of 0.0.
