25318317 ÷ 820 
We're looking to find how many times 820 goes into 25318317.

Going ahead to step 1:
820 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 820

Step 2:
25 divided by 820 is 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 820

Let's proceed to step 3:
The number 820 fits into 253 0 times, leaving a remainder of 253.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 253 to get 253.
Take the next digit (1) from the dividend and append it to 253, then repeat: 2531 / 820

Going ahead to step 4:
820 can be fit into 2531 3 times, resulting in a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 2460 from 2531 leaves us with 71.
Append the next digit (8) from the dividend to 71 and continue with: 718 / 820

Let's proceed to step 5:
The number 820 fits into 718 0 times, leaving a remainder of 718.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 718 and we're left with 718.
Grab the next digit (3) from the dividend, add it to 718, then carry on: 7183 / 820

Step 6:
7183 divided by 820 is 8 with a remainder of 623.
The number 8 becomes the next digit in our result. 
Result so far: 308.0
The remainder is 623 after subtracting 6560 from 7183.
Bring next digit (1) of the dividend behind the 623 and repeat the process: 6231 / 820

Going ahead to step 7:
The number 820 fits into 6231 7 times, leaving a remainder of 491.
Put 7 as the next digit of the answer. 
Result so far: 3087.0
Subtracting 5740 from 6231 leaves us with 491.
Take the next digit (7) from the dividend and append it to 491, then repeat: 4917 / 820

Let's proceed to step 8:
820 goes into 4917 5 times with a remainder of 817.
Record the quotient 5 as the next digit in the result. 
Result so far: 30875.0
If we take 4100 away from 4917, we end up with 817.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8170, and continue the process.

On to step 9:
If we divide 8170 by 820, we get 9 and a remainder of 790.
Use 9 as the next digit of our solution. 
Result so far: 30875.9
The remainder is 790 after subtracting 7380 from 8170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Going ahead to step 10:
7900 divided by 820 is 9 with a remainder of 520.
The next digit of our result is 9. 
Result so far: 30875.99
If we subtract 7380 from 7900, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The final result is 30875.99 with a remainder of 0.52.
