25725677 ÷ 81 
Let's see how many times 81 fits into 25725677.

Step 1:
The number 81 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 81

Step 2:
If we divide 25 by 81, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 81

Advancing to step 3:
The number 81 fits into 257 3 times, leaving a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 243 from 257, we get 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 81

Advancing to step 4:
If we divide 142 by 81, we get 1 and a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
The remainder is 61 after subtracting 81 from 142.
Fetch the next digit (5) from the dividend, attach it to 61 and continue: 615 / 81

Let's proceed to step 5:
If we divide 615 by 81, we get 7 and a remainder of 48.
The next digit of our result is 7. 
Result so far: 317.0
If we take 567 away from 615, we end up with 48.
Include the next digit (6) from the dividend after 48, then repeat: 486 / 81

Advancing to step 6:
81 can be fit into 486 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 3176.0
If we take 486 away from 486, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 81

Step 7:
If we divide 7 by 81, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 31760.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 81

On to step 8:
The number 81 fits into 77 0 times, leaving a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 317600.0
Deduct 0 from 77 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 9:
770 divided by 81 is 9 with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 317600.9
If we subtract 729 from 770, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 10:
If we divide 410 by 81, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 317600.95
If we take 405 away from 410, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
81 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 317600.95
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
If we divide 500 by 81, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 317600.9506
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
The number 81 fits into 140 1 times, leaving a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 317600.95061
If we take 81 away from 140, we end up 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.

Moving on to step 14:
The number 81 fits into 590 7 times, leaving a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 317600.950617
Deduct 567 from 590 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 15:
81 can be fit into 230 2 times, resulting in a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 317600.9506172
The remainder is 68 after subtracting 162 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 16:
The number 81 fits into 680 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 317600.95061728
Subtract 648 from 680 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 317600.95061728, with a leftover of 3.2e-08.
