We look at the division of 115509 by 10 
Our goal is to divide 115509 by 10.

Going ahead to step 1:
The number 10 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 10

Let's proceed to step 2:
10 can be fit into 11 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 10 from 11 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 10

Moving on to step 3:
The number 10 fits into 15 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 5 after subtracting 10 from 15.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 10

Step 4:
10 can be fit into 55 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 115.0
If we take 50 away from 55, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 10

On to step 5:
When dividing 50 by 10, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1155.0
The remainder is 0 after subtracting 50 from 50.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 10

Step 6:
When dividing 9 by 10, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 11550.0
The remainder is 9 after subtracting 0 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
90 divided by 10 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 11550.9
Deduct 90 from 90 and we're left 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.

Advancing to step 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11550.9
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.

Advancing to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11550.9
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.

The quotient of the division is 11550.9, and the remainder is 0.0.
