53849302 ÷ 823 
Let's see how many times 823 fits into 53849302.

Advancing to step 1:
5 divided by 823 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 823

Going ahead to step 2:
The number 823 fits into 53 0 times, leaving a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 823

Step 3:
If we divide 538 by 823, we get 0 and a remainder of 538.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 538 leaves us with 538.
Bring next digit (4) of the dividend behind the 538 and repeat the process: 5384 / 823

On to step 4:
823 goes into 5384 6 times with a remainder of 446.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 446 after subtracting 4938 from 5384.
Take the next digit (9) from the dividend and append it to 446, then repeat: 4469 / 823

Going ahead to step 5:
4469 divided by 823 is 5 with a remainder of 354.
The next digit of our result is 5. 
Result so far: 65.0
Subtracting 4115 from 4469 leaves us with 354.
Include the next digit (3) from the dividend after 354, then repeat: 3543 / 823

Step 6:
When dividing 3543 by 823, we get 4 with a remainder of 251.
Record the quotient 4 as the next digit in the result. 
Result so far: 654.0
If we subtract 3292 from 3543, we get 251.
Bring next digit (0) of the dividend behind the 251 and repeat the process: 2510 / 823

Let's proceed to step 7:
If we divide 2510 by 823, we get 3 and a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 6543.0
Deduct 2469 from 2510 and we're left with 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 823

Let's proceed to step 8:
823 goes into 412 0 times with a remainder of 412.
Write down 0 as next digit of the result. 
Result so far: 65430.0
Subtract 0 from 412 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 9:
823 can be fit into 4120 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 65430.5
Subtracting 4115 from 4120 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
823 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 65430.5
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
When dividing 500 by 823, we get 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 65430.5
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 65430.5 and a remainder of 0.05.
