491780 ÷ 99 
We want to figure out the number of times 491780 can be divided by 99.

On to step 1:
99 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 99

Moving on to step 2:
49 divided by 99 is 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 99

Going ahead to step 3:
When dividing 491 by 99, we get 4 with a remainder of 95.
The next digit of our result is 4. 
Result so far: 4.0
If we take 396 away from 491, we end up with 95.
Fetch the next digit (7) from the dividend, attach it to 95 and continue: 957 / 99

Advancing to step 4:
When dividing 957 by 99, we get 9 with a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 49.0
The remainder is 66 after subtracting 891 from 957.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 99

Let's proceed to step 5:
99 goes into 668 6 times with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 496.0
Subtract 594 from 668 to get 74.
Include the next digit (0) from the dividend after 74, then repeat: 740 / 99

Step 6:
99 goes into 740 7 times with a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 4967.0
Subtract 693 from 740 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
When dividing 470 by 99, we get 4 with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 4967.4
Subtract 396 from 470 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 8:
99 goes into 740 7 times with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 4967.47
Subtract 693 from 740 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
99 goes into 470 4 times with a remainder of 74.
The next digit of our result is 4. 
Result so far: 4967.474
The remainder is 74 after subtracting 396 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 10:
If we divide 740 by 99, we get 7 and a remainder of 47.
The next digit of our result is 7. 
Result so far: 4967.4747
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 11:
470 divided by 99 is 4 with a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 4967.47474
Subtract 396 from 470 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 12:
The number 99 fits into 740 7 times, leaving a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 4967.474747
If we take 693 away from 740, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 13:
The number 99 fits into 470 4 times, leaving a remainder of 74.
The next digit of our result is 4. 
Result so far: 4967.4747474
Subtracting 396 from 470 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 14:
When dividing 740 by 99, we get 7 with a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 4967.47474747
If we take 693 away from 740, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

After the division, we end up with 4967.47474747 and a remainder of 4.7e-08.
