515152 ÷ 99 
We want to figure out the number of times 515152 can be divided by 99.

Step 1:
If we divide 5 by 99, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 99

Step 2:
99 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 99

Moving on to step 3:
515 divided by 99 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 495 from 515 and we're left with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 99

Let's proceed to step 4:
If we divide 201 by 99, we get 2 and a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Subtracting 198 from 201 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 99

Let's proceed to step 5:
The number 99 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 520.0
Subtracting 0 from 35 leaves us with 35.
Bring next digit (2) of the dividend behind the 35 and repeat the process: 352 / 99

Step 6:
99 goes into 352 3 times with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 5203.0
The remainder is 55 after subtracting 297 from 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 7:
99 can be fit into 550 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 5203.5
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.

On to step 8:
99 goes into 550 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 5203.55
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.

The final outcome is 5203.55, with a leftover of 0.055.
