Let's divide 25990146 by 816
Let's see how many times 816 fits into 25990146.

Advancing to step 1:
If we divide 2 by 816, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 816

Moving on to step 2:
The number 816 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 816

Advancing to step 3:
When dividing 259 by 816, we get 0 with a remainder of 259.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 259, we get 259.
Fetch the next digit (9) from the dividend, attach it to 259 and continue: 2599 / 816

Moving on to step 4:
816 can be fit into 2599 3 times, resulting in a remainder of 151.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 151 after subtracting 2448 from 2599.
Append the next digit (0) from the dividend to 151 and continue with: 1510 / 816

Advancing to step 5:
816 can be fit into 1510 1 times, resulting in a remainder of 694.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtract 816 from 1510 to get 694.
Bring next digit (1) of the dividend behind the 694 and repeat the process: 6941 / 816

Moving on to step 6:
816 goes into 6941 8 times with a remainder of 413.
Put 8 as the next digit of the answer. 
Result so far: 318.0
Subtracting 6528 from 6941 leaves us with 413.
Fetch the next digit (4) from the dividend, attach it to 413 and continue: 4134 / 816

Step 7:
816 goes into 4134 5 times with a remainder of 54.
The number 5 becomes the next digit in our result. 
Result so far: 3185.0
If we take 4080 away from 4134, we end up with 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 816

Advancing to step 8:
If we divide 546 by 816, we get 0 and a remainder of 546.
Record the quotient 0 as the next digit in the result. 
Result so far: 31850.0
Subtract 0 from 546 to get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Step 9:
5460 divided by 816 is 6 with a remainder of 564.
The number 6 becomes the next digit in our result. 
Result so far: 31850.6
The remainder is 564 after subtracting 4896 from 5460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 10:
The number 816 fits into 5640 6 times, leaving a remainder of 744.
The number 6 becomes the next digit in our result. 
Result so far: 31850.66
Subtracting 4896 from 5640 leaves us with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Our division results in 31850.66 with a remaining 0.744.
