We divide 135504 by 9
We want to figure out the number of times 135504 can be divided by 9.

Step 1:
When dividing 1 by 9, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 9

Let's proceed to step 2:
The number 9 fits into 13 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 9 from 13 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 9

Advancing to step 3:
9 can be fit into 45 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 45 from 45 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 9

Advancing to step 4:
9 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 150.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 9

Going ahead to step 5:
The number 9 fits into 50 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1505.0
Subtracting 45 from 50 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 9

Let's proceed to step 6:
The number 9 fits into 54 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 15056.0
Subtracting 54 from 54 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.

Going ahead to step 7:
0 divided by 9 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15056.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
When dividing 0 by 9, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15056.0
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 final result is 15056.0 with a remainder of 0.0.
