80717257 ÷ 825 
Let's see how many times 825 fits into 80717257.

Going ahead to step 1:
If we divide 8 by 825, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 825

On to step 2:
If we divide 80 by 825, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 825

Let's proceed to step 3:
When dividing 807 by 825, we get 0 with a remainder of 807.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 807, we end up with 807.
Include the next digit (1) from the dividend after 807, then repeat: 8071 / 825

Step 4:
The number 825 fits into 8071 9 times, leaving a remainder of 646.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7425 from 8071, we get 646.
Fetch the next digit (7) from the dividend, attach it to 646 and continue: 6467 / 825

Let's proceed to step 5:
When dividing 6467 by 825, we get 7 with a remainder of 692.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtracting 5775 from 6467 leaves us with 692.
Take the next digit (2) from the dividend and append it to 692, then repeat: 6922 / 825

Let's proceed to step 6:
825 goes into 6922 8 times with a remainder of 322.
Use 8 as the next digit of our solution. 
Result so far: 978.0
If we subtract 6600 from 6922, we get 322.
Bring next digit (5) of the dividend behind the 322 and repeat the process: 3225 / 825

Going ahead to step 7:
If we divide 3225 by 825, we get 3 and a remainder of 750.
Write down 3 as next digit of the result. 
Result so far: 9783.0
Deduct 2475 from 3225 and we're left with 750.
Take the next digit (7) from the dividend and append it to 750, then repeat: 7507 / 825

Advancing to step 8:
7507 divided by 825 is 9 with a remainder of 82.
The number 9 becomes the next digit in our result. 
Result so far: 97839.0
Deduct 7425 from 7507 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 9:
825 can be fit into 820 0 times, resulting in a remainder of 820.
Record the quotient 0 as the next digit in the result. 
Result so far: 97839.0
If we take 0 away from 820, we end up with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Step 10:
825 goes into 8200 9 times with a remainder of 775.
Write down 9 as next digit of the result. 
Result so far: 97839.09
Deduct 7425 from 8200 and we're left with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Let's proceed to step 11:
When dividing 7750 by 825, we get 9 with a remainder of 325.
The number 9 becomes the next digit in our result. 
Result so far: 97839.099
If we subtract 7425 from 7750, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

After the division, we end up with 97839.099 and a remainder of 0.0325.
