803631 ÷ 99 
Let's see how many times 99 fits into 803631.

Let's proceed to step 1:
8 divided by 99 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 99

Going ahead to step 2:
When dividing 80 by 99, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (3) from the dividend after 80, then repeat: 803 / 99

Advancing to step 3:
99 goes into 803 8 times with a remainder of 11.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 792 from 803, we get 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 99

On to step 4:
If we divide 116 by 99, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtracting 99 from 116 leaves us with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 99

Let's proceed to step 5:
99 goes into 173 1 times with a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 811.0
The remainder is 74 after subtracting 99 from 173.
Bring next digit (1) of the dividend behind the 74 and repeat the process: 741 / 99

Moving on to step 6:
99 can be fit into 741 7 times, resulting in a remainder of 48.
The next digit of our result is 7. 
Result so far: 8117.0
If we take 693 away from 741, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
99 goes into 480 4 times with a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 8117.4
Subtracting 396 from 480 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 8:
The number 99 fits into 840 8 times, leaving a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 8117.48
If we take 792 away from 840, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
99 goes into 480 4 times with a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 8117.484
Subtract 396 from 480 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 10:
840 divided by 99 is 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 8117.4848
Deduct 792 from 840 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
If we divide 480 by 99, we get 4 and a remainder of 84.
The next digit of our result is 4. 
Result so far: 8117.48484
Deduct 396 from 480 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
When dividing 840 by 99, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 8117.484848
If we subtract 792 from 840, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 13:
99 goes into 480 4 times with a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 8117.4848484
Subtracting 396 from 480 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 14:
When dividing 840 by 99, we get 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 8117.48484848
Deduct 792 from 840 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 8117.48484848, and the remainder is 4.8e-08.
