We're dividing 25710912 by 812 
Let's see how many times 812 fits into 25710912.

Advancing to step 1:
The number 812 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 812

On to step 2:
When dividing 25 by 812, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 812

Step 3:
The number 812 fits into 257 0 times, leaving a remainder of 257.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 257 to get 257.
Bring next digit (1) of the dividend behind the 257 and repeat the process: 2571 / 812

Moving on to step 4:
When dividing 2571 by 812, we get 3 with a remainder of 135.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2436 from 2571 to get 135.
Take the next digit (0) from the dividend and append it to 135, then repeat: 1350 / 812

Advancing to step 5:
812 goes into 1350 1 times with a remainder of 538.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 812 away from 1350, we end up with 538.
Append the next digit (9) from the dividend to 538 and continue with: 5389 / 812

Advancing to step 6:
When dividing 5389 by 812, we get 6 with a remainder of 517.
The number 6 becomes the next digit in our result. 
Result so far: 316.0
If we take 4872 away from 5389, we end up with 517.
Append the next digit (1) from the dividend to 517 and continue with: 5171 / 812

On to step 7:
5171 divided by 812 is 6 with a remainder of 299.
Record the quotient 6 as the next digit in the result. 
Result so far: 3166.0
The remainder is 299 after subtracting 4872 from 5171.
Fetch the next digit (2) from the dividend, attach it to 299 and continue: 2992 / 812

Advancing to step 8:
2992 divided by 812 is 3 with a remainder of 556.
Record the quotient 3 as the next digit in the result. 
Result so far: 31663.0
If we subtract 2436 from 2992, we get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Advancing to step 9:
The number 812 fits into 5560 6 times, leaving a remainder of 688.
The number 6 becomes the next digit in our result. 
Result so far: 31663.6
Subtracting 4872 from 5560 leaves us with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Let's proceed to step 10:
812 goes into 6880 8 times with a remainder of 384.
Record the quotient 8 as the next digit in the result. 
Result so far: 31663.68
If we subtract 6496 from 6880, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 11:
812 can be fit into 3840 4 times, resulting in a remainder of 592.
Put 4 as the next digit of the answer. 
Result so far: 31663.684
Deduct 3248 from 3840 and we're left with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Going ahead to step 12:
5920 divided by 812 is 7 with a remainder of 236.
Record the quotient 7 as the next digit in the result. 
Result so far: 31663.6847
If we subtract 5684 from 5920, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 13:
The number 812 fits into 2360 2 times, leaving a remainder of 736.
Record the quotient 2 as the next digit in the result. 
Result so far: 31663.68472
Subtracting 1624 from 2360 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Step 14:
The number 812 fits into 7360 9 times, leaving a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 31663.684729
Subtract 7308 from 7360 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 15:
The number 812 fits into 520 0 times, leaving a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 31663.684729
If we subtract 0 from 520, 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.

Let's proceed to step 16:
When dividing 5200 by 812, we get 6 with a remainder of 328.
Use 6 as the next digit of our solution. 
Result so far: 31663.68472906
Deduct 4872 from 5200 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

After the division, we end up with 31663.68472906 and a remainder of 3.28e-07.
