25260447 ÷ 280 
We're looking to find how many times 280 goes into 25260447.

On to step 1:
When dividing 2 by 280, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 280

On to step 2:
If we divide 25 by 280, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 280

Let's proceed to step 3:
If we divide 252 by 280, we get 0 and a remainder of 252.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 252, we end up with 252.
Bring next digit (6) of the dividend behind the 252 and repeat the process: 2526 / 280

Step 4:
280 can be fit into 2526 9 times, resulting in a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 2520 from 2526 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 280

On to step 5:
If we divide 60 by 280, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtract 0 from 60 to get 60.
Grab the next digit (4) from the dividend, add it to 60, then carry on: 604 / 280

Going ahead to step 6:
When dividing 604 by 280, we get 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 902.0
Subtracting 560 from 604 leaves us with 44.
Append the next digit (4) from the dividend to 44 and continue with: 444 / 280

Going ahead to step 7:
444 divided by 280 is 1 with a remainder of 164.
Record the quotient 1 as the next digit in the result. 
Result so far: 9021.0
Subtract 280 from 444 to get 164.
Include the next digit (7) from the dividend after 164, then repeat: 1647 / 280

On to step 8:
When dividing 1647 by 280, we get 5 with a remainder of 247.
Record the quotient 5 as the next digit in the result. 
Result so far: 90215.0
If we subtract 1400 from 1647, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 9:
280 can be fit into 2470 8 times, resulting in a remainder of 230.
Record the quotient 8 as the next digit in the result. 
Result so far: 90215.8
If we take 2240 away from 2470, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 10:
If we divide 2300 by 280, we get 8 and a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 90215.88
If we subtract 2240 from 2300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 90215.88 with a remainder of 0.06.
