Let's divide 495810 by 4
The aim is to understand the frequency of 4 in 495810.

Moving on to step 1:
4 goes into 4 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 4 from 4.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 4

Step 2:
If we divide 9 by 4, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 1 after subtracting 8 from 9.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 4

Going ahead to step 3:
4 can be fit into 15 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 123.0
Deduct 12 from 15 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 4

Let's proceed to step 4:
4 can be fit into 38 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 1239.0
Subtracting 36 from 38 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 4

Moving on to step 5:
21 divided by 4 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 12395.0
Subtracting 20 from 21 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 4

Let's proceed to step 6:
When dividing 10 by 4, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 123952.0
Subtracting 8 from 10 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.

Going ahead to step 7:
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: 123952.5
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:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 123952.5
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.

Advancing to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 123952.5
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.

The final outcome is 123952.5, with a leftover of 0.0.
