We divide 423446 by 15
Let's see how many times 15 fits into 423446.

On to step 1:
4 divided by 15 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 15

Going ahead to step 2:
42 divided by 15 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 30 from 42 and we're left with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 15

Step 3:
15 goes into 123 8 times with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 3 after subtracting 120 from 123.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 15

Moving on 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: 282.0
The remainder is 4 after subtracting 30 from 34.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 15

Let's proceed to step 5:
44 divided by 15 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2822.0
The remainder is 14 after subtracting 30 from 44.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 15

Going ahead to step 6:
15 goes into 146 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 28229.0
Subtracting 135 from 146 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
15 can be fit into 110 7 times, resulting in a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 28229.7
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
50 divided by 15 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 28229.73
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 28229.733
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 28229.733, and the remainder is 0.0005.
