We're dividing 630383 by 42 
We want to divide 630383 by 42.

Moving on to step 1:
42 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
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 42

Step 2:
42 goes into 63 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 42 from 63 and we're left with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 42

Step 3:
When dividing 210 by 42, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 210 from 210 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 42

Advancing to step 4:
42 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 150.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 42

Let's proceed to step 5:
38 divided by 42 is 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 1500.0
Subtract 0 from 38 to get 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 42

Step 6:
The number 42 fits into 383 9 times, leaving a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 15009.0
Subtracting 378 from 383 leaves us 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.

Step 7:
42 can be fit into 50 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 15009.1
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
42 goes into 80 1 times with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 15009.11
Deduct 42 from 80 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 15009.11, with a leftover of 0.038.
