25503924 ÷ 864 
Let's see how many times 864 fits into 25503924.

Moving on to step 1:
864 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 864

Advancing to step 2:
The number 864 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 864

On to step 3:
The number 864 fits into 255 0 times, leaving a remainder of 255.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 255, we get 255.
Fetch the next digit (0) from the dividend, attach it to 255 and continue: 2550 / 864

Let's proceed to step 4:
The number 864 fits into 2550 2 times, leaving a remainder of 822.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1728 from 2550 to get 822.
Include the next digit (3) from the dividend after 822, then repeat: 8223 / 864

Advancing to step 5:
When dividing 8223 by 864, we get 9 with a remainder of 447.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Deduct 7776 from 8223 and we're left with 447.
Grab the next digit (9) from the dividend, add it to 447, then carry on: 4479 / 864

On to step 6:
If we divide 4479 by 864, we get 5 and a remainder of 159.
Use 5 as the next digit of our solution. 
Result so far: 295.0
Deduct 4320 from 4479 and we're left with 159.
Bring next digit (2) of the dividend behind the 159 and repeat the process: 1592 / 864

Step 7:
If we divide 1592 by 864, we get 1 and a remainder of 728.
Put 1 as the next digit of the answer. 
Result so far: 2951.0
The remainder is 728 after subtracting 864 from 1592.
Include the next digit (4) from the dividend after 728, then repeat: 7284 / 864

Going ahead to step 8:
7284 divided by 864 is 8 with a remainder of 372.
The next digit of our result is 8. 
Result so far: 29518.0
Subtract 6912 from 7284 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 9:
When dividing 3720 by 864, we get 4 with a remainder of 264.
The next digit of our result is 4. 
Result so far: 29518.4
If we take 3456 away from 3720, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 10:
The number 864 fits into 2640 3 times, leaving a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 29518.43
The remainder is 48 after subtracting 2592 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
864 can be fit into 480 0 times, resulting in a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 29518.43
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 12:
The number 864 fits into 4800 5 times, leaving a remainder of 480.
The number 5 becomes the next digit in our result. 
Result so far: 29518.4305
The remainder is 480 after subtracting 4320 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 13:
864 can be fit into 4800 5 times, resulting in a remainder of 480.
Write down 5 as next digit of the result. 
Result so far: 29518.43055
Deduct 4320 from 4800 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Our division results in 29518.43055 with a remaining 0.00048.
