515438 ÷ 99 
We want to figure out the number of times 515438 can be divided by 99.

Step 1:
If we divide 5 by 99, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 99

Moving on to step 2:
99 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 99

Going ahead to step 3:
99 goes into 515 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 495 away from 515, we end up with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 99

Step 4:
99 goes into 204 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtracting 198 from 204 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 99

Step 5:
99 can be fit into 63 0 times, resulting in a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 520.0
The remainder is 63 after subtracting 0 from 63.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 99

Advancing to step 6:
The number 99 fits into 638 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 5206.0
Deduct 594 from 638 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
99 goes into 440 4 times with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 5206.4
Subtracting 396 from 440 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
The number 99 fits into 440 4 times, leaving a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 5206.44
Subtracting 396 from 440 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 5206.44 with a balance of 0.044.
