3403882 divided by 823 
Let's see how many times 823 fits into 3403882.

On to step 1:
3 divided by 823 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 823

Moving on to step 2:
If we divide 34 by 823, we get 0 and a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 823

On to step 3:
340 divided by 823 is 0 with a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 340 and we're left with 340.
Bring next digit (3) of the dividend behind the 340 and repeat the process: 3403 / 823

Going ahead to step 4:
When dividing 3403 by 823, we get 4 with a remainder of 111.
The next digit of our result is 4. 
Result so far: 4.0
If we take 3292 away from 3403, we end up with 111.
Bring next digit (8) of the dividend behind the 111 and repeat the process: 1118 / 823

On to step 5:
If we divide 1118 by 823, we get 1 and a remainder of 295.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtracting 823 from 1118 leaves us with 295.
Take the next digit (8) from the dividend and append it to 295, then repeat: 2958 / 823

Advancing to step 6:
823 can be fit into 2958 3 times, resulting in a remainder of 489.
The number 3 becomes the next digit in our result. 
Result so far: 413.0
Subtract 2469 from 2958 to get 489.
Append the next digit (2) from the dividend to 489 and continue with: 4892 / 823

On to step 7:
If we divide 4892 by 823, we get 5 and a remainder of 777.
The next digit of our result is 5. 
Result so far: 4135.0
Subtract 4115 from 4892 to get 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

On to step 8:
If we divide 7770 by 823, we get 9 and a remainder of 363.
Put 9 as the next digit of the answer. 
Result so far: 4135.9
Deduct 7407 from 7770 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Let's proceed to step 9:
If we divide 3630 by 823, we get 4 and a remainder of 338.
Use 4 as the next digit of our solution. 
Result so far: 4135.94
If we take 3292 away from 3630, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 10:
823 can be fit into 3380 4 times, resulting in a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 4135.944
If we subtract 3292 from 3380, we 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.

The quotient of the division is 4135.944, and the remainder is 0.0088.
