We're dividing 515009 by 5 
Our goal is to divide 515009 by 5.

On to step 1:
5 divided by 5 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 5 from 5 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 5

Let's proceed to step 2:
5 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 5

Going ahead to step 3:
5 can be fit into 15 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 103.0
Subtracting 15 from 15 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 5

Going ahead to step 4:
5 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 1030.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 5

On to step 5:
If we divide 0 by 5, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10300.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 5

Let's proceed to step 6:
5 can be fit into 9 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 103001.0
Subtract 5 from 9 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
The number 5 fits into 40 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 103001.8
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 103001.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 5, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 103001.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 103001.8, with a leftover of 0.0.
