251515 divided by 99 
We want to figure out the number of times 251515 can be divided by 99.

Going ahead to step 1:
When dividing 2 by 99, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 99

Step 2:
The number 99 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 99

Going ahead to step 3:
99 can be fit into 251 2 times, resulting in a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 198 from 251 to get 53.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 99

Step 4:
535 divided by 99 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 25.0
The remainder is 40 after subtracting 495 from 535.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 99

Let's proceed to step 5:
The number 99 fits into 401 4 times, leaving a remainder of 5.
The next digit of our result is 4. 
Result so far: 254.0
Deduct 396 from 401 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 99

Step 6:
99 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 2540.0
Subtracting 0 from 55 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
99 goes into 550 5 times with a remainder of 55.
The next digit of our result is 5. 
Result so far: 2540.5
Subtract 495 from 550 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 8:
If we divide 550 by 99, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 2540.55
If we take 495 away from 550, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 2540.55 and a remainder of 0.055.
