We look at the division of 630333 by 42 
We want to figure out the number of times 630333 can be divided by 42.

Going ahead to step 1:
If we divide 6 by 42, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 42

Advancing to step 2:
63 divided by 42 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 42 from 63 to get 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 42

Going ahead to step 3:
When dividing 210 by 42, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 210 away from 210, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 42

On to step 4:
42 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Subtract 0 from 3 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 42

Let's proceed to step 5:
The number 42 fits into 33 0 times, leaving a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 1500.0
Deduct 0 from 33 and we're left with 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 42

On to step 6:
If we divide 333 by 42, we get 7 and a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 15007.0
Subtracting 294 from 333 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
42 can be fit into 390 9 times, resulting in a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 15007.9
The remainder is 12 after subtracting 378 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
42 goes into 120 2 times with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 15007.92
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
If we divide 360 by 42, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 15007.928
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 15007.9285
Deduct 210 from 240 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
When dividing 300 by 42, we get 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 15007.92857
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
42 goes into 60 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 15007.928571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
When dividing 180 by 42, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 15007.9285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
120 divided by 42 is 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 15007.92857142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 15007.92857142 with a remainder of 3.6e-08.
