We divide 256400 by 99
Let's see how many times 99 fits into 256400.

Going ahead to step 1:
2 divided by 99 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in 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 / 99

Advancing to step 2:
The number 99 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.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 99

Advancing to step 3:
99 goes into 256 2 times with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 198 from 256 leaves us with 58.
Bring next digit (4) of the dividend behind the 58 and repeat the process: 584 / 99

Let's proceed to step 4:
When dividing 584 by 99, we get 5 with a remainder of 89.
The next digit of our result is 5. 
Result so far: 25.0
The remainder is 89 after subtracting 495 from 584.
Include the next digit (0) from the dividend after 89, then repeat: 890 / 99

Let's proceed to step 5:
890 divided by 99 is 8 with a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 258.0
Subtract 792 from 890 to get 98.
Grab the next digit (0) from the dividend, add it to 98, then carry on: 980 / 99

On to step 6:
When dividing 980 by 99, we get 9 with a remainder of 89.
Use 9 as the next digit of our solution. 
Result so far: 2589.0
Subtracting 891 from 980 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 7:
99 goes into 890 8 times with a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 2589.8
If we subtract 792 from 890, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 8:
If we divide 980 by 99, we get 9 and a remainder of 89.
Write down 9 as next digit of the result. 
Result so far: 2589.89
Subtracting 891 from 980 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 9:
890 divided by 99 is 8 with a remainder of 98.
Write down 8 as next digit of the result. 
Result so far: 2589.898
Deduct 792 from 890 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
When dividing 980 by 99, we get 9 with a remainder of 89.
Use 9 as the next digit of our solution. 
Result so far: 2589.8989
Deduct 891 from 980 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 11:
99 can be fit into 890 8 times, resulting in a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 2589.89898
If we take 792 away from 890, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 12:
If we divide 980 by 99, we get 9 and a remainder of 89.
The next digit of our result is 9. 
Result so far: 2589.898989
Deduct 891 from 980 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 13:
The number 99 fits into 890 8 times, leaving a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 2589.8989898
If we take 792 away from 890, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 14:
99 goes into 980 9 times with a remainder of 89.
The next digit of our result is 9. 
Result so far: 2589.89898989
If we take 891 away from 980, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

After the division, we end up with 2589.89898989 and a remainder of 8.9e-08.
