489940 ÷ 99 
We want to divide 489940 by 99.

Let's proceed to step 1:
99 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 99

Advancing to step 2:
If we divide 48 by 99, we get 0 and a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 99

On to step 3:
The number 99 fits into 489 4 times, leaving a remainder of 93.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 396 from 489 and we're left with 93.
Append the next digit (9) from the dividend to 93 and continue with: 939 / 99

Let's proceed to step 4:
939 divided by 99 is 9 with a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtract 891 from 939 to get 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 99

Let's proceed to step 5:
When dividing 484 by 99, we get 4 with a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 494.0
If we take 396 away from 484, we end up with 88.
Take the next digit (0) from the dividend and append it to 88, then repeat: 880 / 99

On to step 6:
99 goes into 880 8 times with a remainder of 88.
The next digit of our result is 8. 
Result so far: 4948.0
The remainder is 88 after subtracting 792 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 7:
When dividing 880 by 99, we get 8 with a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 4948.8
Subtract 792 from 880 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 8:
99 goes into 880 8 times with a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 4948.88
If we take 792 away from 880, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Our division results in 4948.88 with a remaining 0.088.
