We look at the division of 423049 by 15 
Let's see how many times 15 fits into 423049.

On to step 1:
4 divided by 15 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 15

Moving on to step 2:
15 goes into 42 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 30 away from 42, we end up with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 15

Going ahead to step 3:
If we divide 123 by 15, we get 8 and a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 120 from 123 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 15

Let's proceed to step 4:
15 goes into 30 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 282.0
The remainder is 0 after subtracting 30 from 30.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 15

Step 5:
If we divide 4 by 15, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 2820.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 15

Moving on to step 6:
15 goes into 49 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 28203.0
The remainder is 4 after subtracting 45 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
15 can be fit into 40 2 times, resulting in a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 28203.2
Deduct 30 from 40 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 28203.26
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 28203.266
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 28203.266 with a remaining 0.001.
