We look at the division of 25791817 by 496 
Our goal is to divide 25791817 by 496.

Step 1:
The number 496 fits into 2 0 times, leaving 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.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 496

Step 2:
If we divide 25 by 496, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 496

Step 3:
496 goes into 257 0 times with a remainder of 257.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 257 leaves us with 257.
Append the next digit (9) from the dividend to 257 and continue with: 2579 / 496

On to step 4:
2579 divided by 496 is 5 with a remainder of 99.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 99 after subtracting 2480 from 2579.
Take the next digit (1) from the dividend and append it to 99, then repeat: 991 / 496

On to step 5:
991 divided by 496 is 1 with a remainder of 495.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we take 496 away from 991, we end up with 495.
Append the next digit (8) from the dividend to 495 and continue with: 4958 / 496

Moving on to step 6:
If we divide 4958 by 496, we get 9 and a remainder of 494.
The next digit of our result is 9. 
Result so far: 519.0
Deduct 4464 from 4958 and we're left with 494.
Append the next digit (1) from the dividend to 494 and continue with: 4941 / 496

Moving on to step 7:
When dividing 4941 by 496, we get 9 with a remainder of 477.
The number 9 becomes the next digit in our result. 
Result so far: 5199.0
If we subtract 4464 from 4941, we get 477.
Grab the next digit (7) from the dividend, add it to 477, then carry on: 4777 / 496

Step 8:
If we divide 4777 by 496, we get 9 and a remainder of 313.
Record the quotient 9 as the next digit in the result. 
Result so far: 51999.0
Deduct 4464 from 4777 and we're left with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Going ahead to step 9:
496 can be fit into 3130 6 times, resulting in a remainder of 154.
Write down 6 as next digit of the result. 
Result so far: 51999.6
The remainder is 154 after subtracting 2976 from 3130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 10:
If we divide 1540 by 496, we get 3 and a remainder of 52.
The next digit of our result is 3. 
Result so far: 51999.63
The remainder is 52 after subtracting 1488 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
496 can be fit into 520 1 times, resulting in a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 51999.631
Deduct 496 from 520 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
When dividing 240 by 496, we get 0 with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 51999.631
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 13:
If we divide 2400 by 496, we get 4 and a remainder of 416.
Put 4 as the next digit of the answer. 
Result so far: 51999.63104
Subtract 1984 from 2400 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 14:
The number 496 fits into 4160 8 times, leaving a remainder of 192.
The next digit of our result is 8. 
Result so far: 51999.631048
Deduct 3968 from 4160 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 15:
1920 divided by 496 is 3 with a remainder of 432.
The next digit of our result is 3. 
Result so far: 51999.6310483
The remainder is 432 after subtracting 1488 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 16:
4320 divided by 496 is 8 with a remainder of 352.
The next digit of our result is 8. 
Result so far: 51999.63104838
Deduct 3968 from 4320 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

After the division, we end up with 51999.63104838 and a remainder of 3.52e-07.
