We're dividing 428014 by 15 
Let's see how many times 15 fits into 428014.

Going ahead to step 1:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 15

Let's proceed to step 2:
15 goes into 42 2 times with a remainder of 12.
Write down 2 as next digit of 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

Step 3:
If we divide 128 by 15, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 120 from 128 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 15

Step 4:
When dividing 80 by 15, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 285.0
Subtract 75 from 80 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 15

Advancing to step 5:
If we divide 51 by 15, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 2853.0
The remainder is 6 after subtracting 45 from 51.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 15

Going ahead to step 6:
If we divide 64 by 15, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 28534.0
Subtracting 60 from 64 leaves us with 4.
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.
Record the quotient 2 as the next digit in the result. 
Result so far: 28534.2
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.

Step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 28534.26
If we subtract 90 from 100, we 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.

Going ahead to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 28534.266
Deduct 90 from 100 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.

The final outcome is 28534.266, with a leftover of 0.001.
