420296 divided by 15 
We're looking to find how many times 15 goes into 420296.

On to step 1:
15 can be fit into 4 0 times, resulting in 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.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 15

Let's proceed to step 2:
When dividing 42 by 15, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 12 after subtracting 30 from 42.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 15

On to step 3:
15 goes into 120 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 28.0
If we subtract 120 from 120, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 15

Going ahead to step 4:
If we divide 2 by 15, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 280.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 15

Let's proceed to step 5:
When dividing 29 by 15, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 2801.0
Subtract 15 from 29 to get 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 15

Advancing to step 6:
146 divided by 15 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 28019.0
If we subtract 135 from 146, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
When dividing 110 by 15, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 28019.7
If we subtract 105 from 110, we 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.

Step 8:
50 divided by 15 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 28019.73
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.

On to step 9:
15 goes into 50 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 28019.733
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.

In conclusion, the division gives 28019.733 with a balance of 0.0005.
