We're dividing 123480 by 15 
We want to divide 123480 by 15.

Let's proceed to step 1:
The number 15 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 (2) from the dividend, attach it to 1 and continue: 12 / 15

Going ahead to step 2:
15 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 15

On to step 3:
The number 15 fits into 123 8 times, leaving a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 120 from 123 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 15

Going ahead to step 4:
When dividing 34 by 15, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
If we take 30 away from 34, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 15

Let's proceed to step 5:
48 divided by 15 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 823.0
Subtracting 45 from 48 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 15

Step 6:
15 goes into 30 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 8232.0
Subtracting 30 from 30 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.

Moving on to step 7:
When dividing 0 by 15, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8232.0
If we subtract 0 from 0, we 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.

On to step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8232.0
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.

After the division, we end up with 8232.0 and a remainder of 0.0.
