823 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 823

On to step 2:
The number 823 fits into 29 0 times, leaving a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 823

Moving on to step 3:
If we divide 296 by 823, we get 0 and a remainder of 296.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 296, we get 296.
Include the next digit (1) from the dividend after 296, then repeat: 2961 / 823

Advancing to step 4:
The number 823 fits into 2961 3 times, leaving a remainder of 492.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 492 after subtracting 2469 from 2961.
Include the next digit (2) from the dividend after 492, then repeat: 4922 / 823

Advancing to step 5:
When dividing 4922 by 823, we get 5 with a remainder of 807.
Write down 5 as next digit of the result. 
Result so far: 35.0
The remainder is 807 after subtracting 4115 from 4922.
Include the next digit (8) from the dividend after 807, then repeat: 8078 / 823

Going ahead to step 6:
823 can be fit into 8078 9 times, resulting in a remainder of 671.
Write down 9 as next digit of the result. 
Result so far: 359.0
Subtract 7407 from 8078 to get 671.
Bring next digit (2) of the dividend behind the 671 and repeat the process: 6712 / 823

Going ahead to step 7:
6712 divided by 823 is 8 with a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 3598.0
Subtract 6584 from 6712 to get 128.
Append the next digit (1) from the dividend to 128 and continue with: 1281 / 823

Moving on to step 8:
823 goes into 1281 1 times with a remainder of 458.
The next digit of our result is 1. 
Result so far: 35981.0
If we subtract 823 from 1281, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Step 9:
The number 823 fits into 4580 5 times, leaving a remainder of 465.
Record the quotient 5 as the next digit in the result. 
Result so far: 35981.5
The remainder is 465 after subtracting 4115 from 4580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Moving on to step 10:
823 goes into 4650 5 times with a remainder of 535.
The next digit of our result is 5. 
Result so far: 35981.55
The remainder is 535 after subtracting 4115 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Our division results in 35981.55 with a remaining 0.535.
