We're dividing 630076 by 15 
Let's see how many times 15 fits into 630076.

On to step 1:
15 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 15

Step 2:
The number 15 fits into 63 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 60 from 63 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 15

On to step 3:
When dividing 30 by 15, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 42.0
The remainder is 0 after subtracting 30 from 30.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 15

On to step 4:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 420.0
If we take 0 away from 0, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 15

Step 5:
If we divide 7 by 15, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 4200.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 15

Going ahead to step 6:
When dividing 76 by 15, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 42005.0
Subtract 75 from 76 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
15 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 42005.0
If we subtract 0 from 10, 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 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 42005.06
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.

Step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 42005.066
The remainder is 10 after subtracting 90 from 100.
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 outcome is 42005.066, with a leftover of 0.001.
