We look at the division of 454124 by 15 
Our goal is to divide 454124 by 15.

Let's proceed to step 1:
If we divide 4 by 15, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 15

Going ahead to step 2:
The number 15 fits into 45 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 0 after subtracting 45 from 45.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 15

On to step 3:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 15

Step 4:
15 goes into 41 2 times with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 302.0
Deduct 30 from 41 and we're left with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 15

Let's proceed to step 5:
When dividing 112 by 15, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 3027.0
If we take 105 away from 112, we end up with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 15

Step 6:
When dividing 74 by 15, we get 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 30274.0
The remainder is 14 after subtracting 60 from 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 15 is 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 30274.9
If we subtract 135 from 140, 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.

On to step 8:
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: 30274.93
If we take 45 away from 50, we end up 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.

Going ahead to step 9:
15 goes into 50 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 30274.933
Subtract 45 from 50 to 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.

The quotient of the division is 30274.933, and the remainder is 0.0005.
