We're dividing 878049 by 15 
Let's see how many times 15 fits into 878049.

Let's proceed to step 1:
15 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 15

Let's proceed to step 2:
The number 15 fits into 87 5 times, leaving a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 75 from 87 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 15

Moving on to step 3:
15 goes into 128 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 58.0
The remainder is 8 after subtracting 120 from 128.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 15

On to step 4:
If we divide 80 by 15, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 585.0
Subtracting 75 from 80 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 15

Let's proceed to step 5:
The number 15 fits into 54 3 times, leaving a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 5853.0
Subtracting 45 from 54 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 15

Advancing to step 6:
If we divide 99 by 15, we get 6 and a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 58536.0
If we subtract 90 from 99, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
15 can be fit into 90 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 58536.6
Subtract 90 from 90 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.

Step 8:
0 divided by 15 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 58536.6
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.

Advancing to step 9:
When dividing 0 by 15, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 58536.6
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.

The final result is 58536.6 with a remainder of 0.0.
