453385 ÷ 15 
We want to divide 453385 by 15.

Step 1:
When dividing 4 by 15, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 15

Step 2:
45 divided by 15 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 45 from 45, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 15

On to step 3:
The number 15 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 30.0
Subtract 0 from 3 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 15

Moving on to step 4:
The number 15 fits into 33 2 times, leaving a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 302.0
Subtracting 30 from 33 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 15

Let's proceed to step 5:
If we divide 38 by 15, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 3022.0
Deduct 30 from 38 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 15

On to step 6:
15 goes into 85 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 30225.0
Subtracting 75 from 85 leaves us 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.

Let's proceed to step 7:
100 divided by 15 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 30225.6
If we take 90 away from 100, we end up 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.

Moving on to step 8:
100 divided by 15 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 30225.66
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.

After the division, we end up with 30225.66 and a remainder of 0.01.
