1509 divided by 99 
Our goal is to divide 1509 by 99.

Step 1:
When dividing 1 by 99, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 99

Advancing to step 2:
99 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 99

On to step 3:
The number 99 fits into 150 1 times, leaving a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 99 from 150, we get 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 99

Going ahead to step 4:
99 can be fit into 519 5 times, resulting in a remainder of 24.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 495 from 519, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 5:
99 can be fit into 240 2 times, resulting in a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 15.2
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 6:
420 divided by 99 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 15.24
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
When dividing 240 by 99, we get 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 15.242
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
When dividing 420 by 99, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 15.2424
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
99 can be fit into 240 2 times, resulting in a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 15.24242
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
99 can be fit into 420 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 15.242424
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
99 goes into 240 2 times with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 15.2424242
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
If we divide 420 by 99, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 15.24242424
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 15.24242424, and the remainder is 2.4e-08.
