We look at the division of 489784 by 1 
We're looking to find how many times 1 goes into 489784.

On to step 1:
1 goes into 4 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 0 after subtracting 4 from 4.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Step 2:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtract 8 from 8 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Let's proceed to step 3:
If we divide 9 by 1, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 489.0
If we subtract 9 from 9, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Let's proceed to step 4:
1 goes into 7 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 4897.0
If we take 7 away from 7, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Going ahead to step 5:
8 divided by 1 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 48978.0
Subtract 8 from 8 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Moving on to step 6:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 489784.0
Subtracting 4 from 4 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.

Step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 489784.0
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.

Let's proceed to step 8:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 489784.0
Subtracting 0 from 0 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.

The final result is 489784.0 with a remainder of 0.0.
