We look at the division of 17257893 by 823 
We're looking to find how many times 823 goes into 17257893.

Let's proceed to step 1:
If we divide 1 by 823, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 823

Let's proceed to step 2:
823 can be fit into 17 0 times, resulting in a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 823

On to step 3:
823 goes into 172 0 times with a remainder of 172.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 172 leaves us with 172.
Bring next digit (5) of the dividend behind the 172 and repeat the process: 1725 / 823

Let's proceed to step 4:
823 goes into 1725 2 times with a remainder of 79.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1646 from 1725, we get 79.
Bring next digit (7) of the dividend behind the 79 and repeat the process: 797 / 823

Moving on to step 5:
If we divide 797 by 823, we get 0 and a remainder of 797.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 797, we get 797.
Fetch the next digit (8) from the dividend, attach it to 797 and continue: 7978 / 823

Step 6:
7978 divided by 823 is 9 with a remainder of 571.
Put 9 as the next digit of the answer. 
Result so far: 209.0
Deduct 7407 from 7978 and we're left with 571.
Include the next digit (9) from the dividend after 571, then repeat: 5719 / 823

Advancing to step 7:
823 can be fit into 5719 6 times, resulting in a remainder of 781.
The number 6 becomes the next digit in our result. 
Result so far: 2096.0
If we take 4938 away from 5719, we end up with 781.
Fetch the next digit (3) from the dividend, attach it to 781 and continue: 7813 / 823

Let's proceed to step 8:
823 goes into 7813 9 times with a remainder of 406.
Put 9 as the next digit of the answer. 
Result so far: 20969.0
If we subtract 7407 from 7813, we get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 9:
823 goes into 4060 4 times with a remainder of 768.
Use 4 as the next digit of our solution. 
Result so far: 20969.4
Subtracting 3292 from 4060 leaves us with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Step 10:
823 goes into 7680 9 times with a remainder of 273.
The next digit of our result is 9. 
Result so far: 20969.49
Subtracting 7407 from 7680 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 11:
823 goes into 2730 3 times with a remainder of 261.
The next digit of our result is 3. 
Result so far: 20969.493
Deduct 2469 from 2730 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Advancing to step 12:
The number 823 fits into 2610 3 times, leaving a remainder of 141.
The number 3 becomes the next digit in our result. 
Result so far: 20969.4933
Subtracting 2469 from 2610 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

In conclusion, the division gives 20969.4933 with a balance of 0.00141.
