We look at the division of 485355 by 15 
We want to divide 485355 by 15.

Let's proceed to step 1:
15 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 15

Step 2:
If we divide 48 by 15, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 45 from 48 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 15

Let's proceed to step 3:
When dividing 35 by 15, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 32.0
Deduct 30 from 35 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 15

On to step 4:
The number 15 fits into 53 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 323.0
The remainder is 8 after subtracting 45 from 53.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 15

Advancing to step 5:
The number 15 fits into 85 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 3235.0
Deduct 75 from 85 and we're left with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 15

Let's proceed to step 6:
If we divide 105 by 15, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 32357.0
Deduct 105 from 105 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
If we divide 0 by 15, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 32357.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 32357.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 32357.0 with a remainder of 0.0.
