489610 ÷ 4 
The aim is to understand the frequency of 4 in 489610.

Advancing 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.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 4

Moving on to step 2:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 8 from 8, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 4

On to step 3:
4 goes into 9 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Subtract 8 from 9 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 4

Let's proceed to step 4:
4 goes into 16 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 1224.0
If we subtract 16 from 16, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 4

Advancing to step 5:
When dividing 1 by 4, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 12240.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 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: 122402.0
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 7:
When dividing 20 by 4, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 122402.5
If we subtract 20 from 20, we 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 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 122402.5
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.

Step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 122402.5
If we subtract 0 from 0, we 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.

Our division results in 122402.5 with a remaining 0.0.
