We divide 428247 by 15
Let's see how many times 15 fits into 428247.

Let's proceed to step 1:
15 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 15

On to step 2:
15 can be fit into 42 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 12 after subtracting 30 from 42.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 15

On to step 3:
15 goes into 128 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 8 after subtracting 120 from 128.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 15

Advancing to step 4:
82 divided by 15 is 5 with a remainder of 7.
The next digit of our result is 5. 
Result so far: 285.0
Subtracting 75 from 82 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 15

Let's proceed to step 5:
74 divided by 15 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 2854.0
Subtract 60 from 74 to get 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 15

Advancing to step 6:
15 can be fit into 147 9 times, resulting in a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 28549.0
Subtracting 135 from 147 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
The number 15 fits into 120 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 28549.8
Deduct 120 from 120 and we're left 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:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28549.8
Subtracting 0 from 0 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 9:
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: 28549.8
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.

After the division, we end up with 28549.8 and a remainder of 0.0.
