We look at the division of 420272 by 15 
Our goal is to divide 420272 by 15.

Moving on to step 1:
When dividing 4 by 15, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 15

Let's proceed 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
If we take 30 away from 42, we end up with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 15

On to step 3:
When dividing 120 by 15, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtracting 120 from 120 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 15

Step 4:
If we divide 2 by 15, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 280.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 15

Step 5:
27 divided by 15 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 2801.0
Subtract 15 from 27 to get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 15

Going ahead to step 6:
When dividing 122 by 15, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 28018.0
Subtract 120 from 122 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 15 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 28018.1
Subtract 15 from 20 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 28018.13
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
50 divided by 15 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 28018.133
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.

The quotient of the division is 28018.133, and the remainder is 0.0005.
