490801 ÷ 4 
The aim is to understand the frequency of 4 in 490801.

Advancing to step 1:
When dividing 4 by 4, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 4 from 4 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 4

Step 2:
If we divide 9 by 4, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 8 from 9 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 4

On to step 3:
4 can be fit into 10 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 122.0
Deduct 8 from 10 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 4

On to step 4:
4 goes into 28 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 1227.0
Subtract 28 from 28 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 4

Going ahead to step 5:
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: 12270.0
If we subtract 0 from 0, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 4

Step 6:
1 divided by 4 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 122700.0
Deduct 0 from 1 and we're left with 1.
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.
The number 2 becomes the next digit in our result. 
Result so far: 122700.2
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.

Let's proceed to step 8:
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: 122700.25
If we take 20 away from 20, we end up 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.

Advancing to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 122700.25
If we take 0 away from 0, we end up 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.

Moving on to step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 122700.25
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 result is 122700.25 with a remainder of 0.0.
