We look at the division of 513051 by 99 
We want to figure out the number of times 513051 can be divided by 99.

On to step 1:
99 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 99

Let's proceed to step 2:
When dividing 51 by 99, we get 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 99

Step 3:
The number 99 fits into 513 5 times, leaving a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 18 after subtracting 495 from 513.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 99

Going ahead to step 4:
99 goes into 180 1 times with a remainder of 81.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtract 99 from 180 to get 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 99

On to step 5:
If we divide 815 by 99, we get 8 and a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 518.0
If we take 792 away from 815, we end up with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 99

Let's proceed to step 6:
If we divide 231 by 99, we get 2 and a remainder of 33.
The next digit of our result is 2. 
Result so far: 5182.0
Subtracting 198 from 231 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
99 goes into 330 3 times with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 5182.3
If we take 297 away from 330, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 8:
99 can be fit into 330 3 times, resulting in a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 5182.33
Subtract 297 from 330 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Our division results in 5182.33 with a remaining 0.033.
