Let's divide 454646 by 15
Our goal is to divide 454646 by 15.

Going ahead to step 1:
If we divide 4 by 15, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 15

Step 2:
When dividing 45 by 15, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 45 from 45 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 15

Going ahead to step 3:
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: 30.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 15

Step 4:
46 divided by 15 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 303.0
The remainder is 1 after subtracting 45 from 46.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 15

On to step 5:
The number 15 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 3030.0
The remainder is 14 after subtracting 0 from 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 15

Going ahead to step 6:
When dividing 146 by 15, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 30309.0
The remainder is 11 after subtracting 135 from 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 15 fits into 110 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 30309.7
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
50 divided by 15 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 30309.73
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.

Moving on to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 30309.733
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.

Our division results in 30309.733 with a remaining 0.0005.
