489454 divided by 4 
We're looking to find how many times 4 goes into 489454.

Going ahead to step 1:
If we divide 4 by 4, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 4 from 4 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

On to step 2:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 0 after subtracting 8 from 8.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 4

On to step 3:
9 divided by 4 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
If we subtract 8 from 9, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 4

On to step 4:
When dividing 14 by 4, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 1223.0
The remainder is 2 after subtracting 12 from 14.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 4

Moving on to step 5:
4 can be fit into 25 6 times, resulting in a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 12236.0
Subtract 24 from 25 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 4

Moving on to step 6:
When dividing 14 by 4, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 122363.0
Subtracting 12 from 14 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.

Let's proceed to step 7:
20 divided by 4 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 122363.5
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.

Going ahead to step 8:
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: 122363.5
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.

Moving on 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: 122363.5
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 122363.5 with a remainder of 0.0.
