We're dividing 57117212 by 823 
We want to divide 57117212 by 823.

Step 1:
The number 823 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 823

Going ahead to step 2:
57 divided by 823 is 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Grab the next digit (1) from the dividend, add it to 57, then carry on: 571 / 823

Moving on to step 3:
The number 823 fits into 571 0 times, leaving a remainder of 571.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 571, we get 571.
Grab the next digit (1) from the dividend, add it to 571, then carry on: 5711 / 823

Step 4:
If we divide 5711 by 823, we get 6 and a remainder of 773.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 4938 from 5711 to get 773.
Grab the next digit (7) from the dividend, add it to 773, then carry on: 7737 / 823

Advancing to step 5:
If we divide 7737 by 823, we get 9 and a remainder of 330.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Subtracting 7407 from 7737 leaves us with 330.
Grab the next digit (2) from the dividend, add it to 330, then carry on: 3302 / 823

Let's proceed to step 6:
3302 divided by 823 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 694.0
Deduct 3292 from 3302 and we're left with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 823

Advancing to step 7:
823 goes into 101 0 times with a remainder of 101.
The next digit of our result is 0. 
Result so far: 6940.0
Subtracting 0 from 101 leaves us with 101.
Bring next digit (2) of the dividend behind the 101 and repeat the process: 1012 / 823

On to step 8:
823 goes into 1012 1 times with a remainder of 189.
The number 1 becomes the next digit in our result. 
Result so far: 69401.0
If we subtract 823 from 1012, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Moving on to step 9:
If we divide 1890 by 823, we get 2 and a remainder of 244.
Write down 2 as next digit of the result. 
Result so far: 69401.2
The remainder is 244 after subtracting 1646 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 10:
The number 823 fits into 2440 2 times, leaving a remainder of 794.
The next digit of our result is 2. 
Result so far: 69401.22
Deduct 1646 from 2440 and we're left with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

The quotient of the division is 69401.22, and the remainder is 0.794.
