We look at the division of 515513 by 9 
We want to figure out the number of times 515513 can be divided by 9.

Let's proceed to step 1:
9 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 9

Going ahead to step 2:
9 can be fit into 51 5 times, resulting in a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 45 from 51 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 9

Step 3:
The number 9 fits into 65 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Subtract 63 from 65 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 9

Step 4:
25 divided by 9 is 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 572.0
The remainder is 7 after subtracting 18 from 25.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 9

On to step 5:
If we divide 71 by 9, we get 7 and a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 5727.0
If we subtract 63 from 71, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 9

Going ahead to step 6:
9 goes into 83 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 57279.0
The remainder is 2 after subtracting 81 from 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
If we divide 20 by 9, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 57279.2
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 9 fits into 20 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 57279.22
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 57279.22, with a leftover of 0.002.
