We divide 409485 by 15
We're looking to find how many times 15 goes into 409485.

Moving on to step 1:
4 divided by 15 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 15

Going ahead to step 2:
15 goes into 40 2 times with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 30 from 40 and we're left with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 15

Let's proceed to step 3:
When dividing 109 by 15, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtract 105 from 109 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 15

Step 4:
44 divided by 15 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 272.0
If we take 30 away from 44, we end up with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 15

Moving on to step 5:
The number 15 fits into 148 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 2729.0
Subtracting 135 from 148 leaves us with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 15

Step 6:
When dividing 135 by 15, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 27299.0
The remainder is 0 after subtracting 135 from 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 27299.0
If we take 0 away from 0, we end up 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.

Step 8:
0 divided by 15 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 27299.0
If we take 0 away from 0, we end up 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.

Our division results in 27299.0 with a remaining 0.0.
