25867685 ÷ 813 
We're looking to find how many times 813 goes into 25867685.

Step 1:
The number 813 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 813

On to step 2:
813 can be fit into 25 0 times, resulting in a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 813

Step 3:
813 goes into 258 0 times with a remainder of 258.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 258 leaves us with 258.
Append the next digit (6) from the dividend to 258 and continue with: 2586 / 813

On to step 4:
813 can be fit into 2586 3 times, resulting in a remainder of 147.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 2439 from 2586 leaves us with 147.
Grab the next digit (7) from the dividend, add it to 147, then carry on: 1477 / 813

Advancing to step 5:
1477 divided by 813 is 1 with a remainder of 664.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtract 813 from 1477 to get 664.
Grab the next digit (6) from the dividend, add it to 664, then carry on: 6646 / 813

Let's proceed to step 6:
The number 813 fits into 6646 8 times, leaving a remainder of 142.
Put 8 as the next digit of the answer. 
Result so far: 318.0
If we take 6504 away from 6646, we end up with 142.
Grab the next digit (8) from the dividend, add it to 142, then carry on: 1428 / 813

Step 7:
When dividing 1428 by 813, we get 1 with a remainder of 615.
The number 1 becomes the next digit in our result. 
Result so far: 3181.0
Subtracting 813 from 1428 leaves us with 615.
Grab the next digit (5) from the dividend, add it to 615, then carry on: 6155 / 813

On to step 8:
6155 divided by 813 is 7 with a remainder of 464.
The next digit of our result is 7. 
Result so far: 31817.0
Deduct 5691 from 6155 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 9:
The number 813 fits into 4640 5 times, leaving a remainder of 575.
Write down 5 as next digit of the result. 
Result so far: 31817.5
If we subtract 4065 from 4640, we get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Let's proceed to step 10:
5750 divided by 813 is 7 with a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 31817.57
Subtract 5691 from 5750 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 11:
590 divided by 813 is 0 with a remainder of 590.
Write down 0 as next digit of the result. 
Result so far: 31817.57
Deduct 0 from 590 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 12:
5900 divided by 813 is 7 with a remainder of 209.
The number 7 becomes the next digit in our result. 
Result so far: 31817.5707
Subtract 5691 from 5900 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 13:
2090 divided by 813 is 2 with a remainder of 464.
Write down 2 as next digit of the result. 
Result so far: 31817.57072
Subtract 1626 from 2090 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 14:
4640 divided by 813 is 5 with a remainder of 575.
The next digit of our result is 5. 
Result so far: 31817.570725
If we subtract 4065 from 4640, we get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Step 15:
5750 divided by 813 is 7 with a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 31817.5707257
Deduct 5691 from 5750 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 16:
When dividing 590 by 813, we get 0 with a remainder of 590.
Record the quotient 0 as the next digit in the result. 
Result so far: 31817.5707257
Subtract 0 from 590 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

In conclusion, the division gives 31817.5707257 with a balance of 5.9e-07.
