25813888 ÷ 455 
Our goal is to divide 25813888 by 455.

Step 1:
When dividing 2 by 455, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 455

Step 2:
If we divide 25 by 455, 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.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 455

On to step 3:
258 divided by 455 is 0 with a remainder of 258.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 258 after subtracting 0 from 258.
Include the next digit (1) from the dividend after 258, then repeat: 2581 / 455

Moving on to step 4:
If we divide 2581 by 455, we get 5 and a remainder of 306.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 306 after subtracting 2275 from 2581.
Include the next digit (3) from the dividend after 306, then repeat: 3063 / 455

Step 5:
If we divide 3063 by 455, we get 6 and a remainder of 333.
Use 6 as the next digit of our solution. 
Result so far: 56.0
The remainder is 333 after subtracting 2730 from 3063.
Grab the next digit (8) from the dividend, add it to 333, then carry on: 3338 / 455

Going ahead to step 6:
When dividing 3338 by 455, we get 7 with a remainder of 153.
Use 7 as the next digit of our solution. 
Result so far: 567.0
The remainder is 153 after subtracting 3185 from 3338.
Append the next digit (8) from the dividend to 153 and continue with: 1538 / 455

Step 7:
The number 455 fits into 1538 3 times, leaving a remainder of 173.
Write down 3 as next digit of the result. 
Result so far: 5673.0
Deduct 1365 from 1538 and we're left with 173.
Append the next digit (8) from the dividend to 173 and continue with: 1738 / 455

Step 8:
455 can be fit into 1738 3 times, resulting in a remainder of 373.
The number 3 becomes the next digit in our result. 
Result so far: 56733.0
If we take 1365 away from 1738, we end up with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

On to step 9:
When dividing 3730 by 455, we get 8 with a remainder of 90.
Put 8 as the next digit of the answer. 
Result so far: 56733.8
The remainder is 90 after subtracting 3640 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
The number 455 fits into 900 1 times, leaving a remainder of 445.
The number 1 becomes the next digit in our result. 
Result so far: 56733.81
Subtracting 455 from 900 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 11:
When dividing 4450 by 455, we get 9 with a remainder of 355.
Write down 9 as next digit of the result. 
Result so far: 56733.819
Deduct 4095 from 4450 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Going ahead to step 12:
455 goes into 3550 7 times with a remainder of 365.
The number 7 becomes the next digit in our result. 
Result so far: 56733.8197
The remainder is 365 after subtracting 3185 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 13:
455 can be fit into 3650 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 56733.81978
The remainder is 10 after subtracting 3640 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
If we divide 100 by 455, we get 0 and a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 56733.81978
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
455 goes into 1000 2 times with a remainder of 90.
Record the quotient 2 as the next digit in the result. 
Result so far: 56733.8197802
Deduct 910 from 1000 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 16:
455 goes into 900 1 times with a remainder of 445.
Write down 1 as next digit of the result. 
Result so far: 56733.81978021
If we subtract 455 from 900, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

In conclusion, the division gives 56733.81978021 with a balance of 4.45e-07.
