We're dividing 454802 by 15 
We're looking to find how many times 15 goes into 454802.

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 take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 15

Moving on to step 2:
45 divided by 15 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 45 from 45, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 15

Going ahead to step 3:
15 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 4, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 15

On to step 4:
When dividing 48 by 15, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 303.0
Deduct 45 from 48 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 15

Moving on to step 5:
30 divided by 15 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 3032.0
Subtract 30 from 30 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 15

Advancing to step 6:
15 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 30320.0
Subtracting 0 from 2 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 15 fits into 20 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 30320.1
Subtracting 15 from 20 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.

Let's proceed to 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: 30320.13
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.

Let's proceed to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 30320.133
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 final outcome is 30320.133, with a leftover of 0.0005.
