We divide 25 by 98
We want to divide 25 by 98.

Step 1:
98 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
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 / 98

On to step 2:
98 goes into 25 0 times with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 3:
98 can be fit into 250 2 times, resulting in a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 0.2
The remainder is 54 after subtracting 196 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 4:
When dividing 540 by 98, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 0.25
The remainder is 50 after subtracting 490 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 5:
The number 98 fits into 500 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 0.255
If we subtract 490 from 500, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 0.255 with a remainder of 0.001.
