25549359 ÷ 728 
We're looking to find how many times 728 goes into 25549359.

Let's proceed to step 1:
2 divided by 728 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 728

Moving on to step 2:
The number 728 fits into 25 0 times, leaving 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.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 728

Advancing to step 3:
255 divided by 728 is 0 with a remainder of 255.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 255 leaves us with 255.
Grab the next digit (4) from the dividend, add it to 255, then carry on: 2554 / 728

On to step 4:
When dividing 2554 by 728, we get 3 with a remainder of 370.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2184 from 2554 and we're left with 370.
Take the next digit (9) from the dividend and append it to 370, then repeat: 3709 / 728

Going ahead to step 5:
When dividing 3709 by 728, we get 5 with a remainder of 69.
The next digit of our result is 5. 
Result so far: 35.0
If we take 3640 away from 3709, we end up with 69.
Grab the next digit (3) from the dividend, add it to 69, then carry on: 693 / 728

Let's proceed to step 6:
If we divide 693 by 728, we get 0 and a remainder of 693.
Put 0 as the next digit of the answer. 
Result so far: 350.0
Subtract 0 from 693 to get 693.
Fetch the next digit (5) from the dividend, attach it to 693 and continue: 6935 / 728

Let's proceed to step 7:
728 goes into 6935 9 times with a remainder of 383.
The number 9 becomes the next digit in our result. 
Result so far: 3509.0
Subtracting 6552 from 6935 leaves us with 383.
Fetch the next digit (9) from the dividend, attach it to 383 and continue: 3839 / 728

Going ahead to step 8:
3839 divided by 728 is 5 with a remainder of 199.
The next digit of our result is 5. 
Result so far: 35095.0
The remainder is 199 after subtracting 3640 from 3839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 9:
If we divide 1990 by 728, we get 2 and a remainder of 534.
The number 2 becomes the next digit in our result. 
Result so far: 35095.2
Subtract 1456 from 1990 to get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Step 10:
728 can be fit into 5340 7 times, resulting in a remainder of 244.
Use 7 as the next digit of our solution. 
Result so far: 35095.27
Deduct 5096 from 5340 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 11:
728 goes into 2440 3 times with a remainder of 256.
Record the quotient 3 as the next digit in the result. 
Result so far: 35095.273
Deduct 2184 from 2440 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 12:
The number 728 fits into 2560 3 times, leaving a remainder of 376.
Record the quotient 3 as the next digit in the result. 
Result so far: 35095.2733
If we take 2184 away from 2560, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The final outcome is 35095.2733, with a leftover of 0.00376.
