We look at the division of 489184 by 45 
Let's see how many times 45 fits into 489184.

Step 1:
When dividing 4 by 45, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 45

Let's proceed to step 2:
The number 45 fits into 48 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 45 away from 48, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 45

Let's proceed to step 3:
If we divide 39 by 45, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 45

Going ahead to step 4:
45 goes into 391 8 times with a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 108.0
The remainder is 31 after subtracting 360 from 391.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 45

Moving on to step 5:
45 can be fit into 318 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 1087.0
The remainder is 3 after subtracting 315 from 318.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 45

On to step 6:
34 divided by 45 is 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 10870.0
Deduct 0 from 34 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
If we divide 340 by 45, we get 7 and a remainder of 25.
The next digit of our result is 7. 
Result so far: 10870.7
Subtracting 315 from 340 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 10870.75
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
45 can be fit into 250 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 10870.755
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 10870.755 with a remainder of 0.0025.
