We look at the division of 454912 by 15 
Our goal is to divide 454912 by 15.

Moving on to step 1:
15 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 15

On to step 2:
15 can be fit into 45 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 45 from 45 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 15

On to step 3:
15 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 15

Going ahead to step 4:
The number 15 fits into 49 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 303.0
Deduct 45 from 49 and we're left with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 15

Step 5:
When dividing 41 by 15, we get 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 3032.0
Subtracting 30 from 41 leaves us with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 15

Moving on to step 6:
15 goes into 112 7 times with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 30327.0
Subtract 105 from 112 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
When dividing 70 by 15, we get 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 30327.4
Subtracting 60 from 70 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.

Step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 30327.46
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 30327.466
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 30327.466 with a remainder of 0.001.
