Let's divide 420349 by 30
Let's see how many times 30 fits into 420349.

Moving on to step 1:
When dividing 4 by 30, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 30

Going ahead to step 2:
The number 30 fits into 42 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 30 from 42 and we're left with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 30

On to step 3:
When dividing 120 by 30, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 120 from 120 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 30

Moving on to step 4:
30 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 140.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 30

Step 5:
30 can be fit into 34 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1401.0
If we subtract 30 from 34, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 30

Advancing to step 6:
30 goes into 49 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 14011.0
Subtract 30 from 49 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
If we divide 190 by 30, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 14011.6
If we take 180 away from 190, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
30 goes into 100 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 14011.63
Subtract 90 from 100 to 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.

Let's proceed to step 9:
100 divided by 30 is 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 14011.633
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 14011.633 and a remainder of 0.001.
