Let's divide 420935 by 30
Our goal is to divide 420935 by 30.

Going ahead to step 1:
30 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 30

On to step 2:
If we divide 42 by 30, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 30 away from 42, we end up with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 30

Advancing to step 3:
120 divided by 30 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 120 from 120, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 30

Moving on to step 4:
The number 30 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 30

On to step 5:
30 can be fit into 93 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 1403.0
Subtract 90 from 93 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 30

On to step 6:
When dividing 35 by 30, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 14031.0
Deduct 30 from 35 and we're left 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.

On to step 7:
30 goes into 50 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 14031.1
If we subtract 30 from 50, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 14031.16
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
30 goes into 200 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 14031.166
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 14031.166, with a leftover of 0.002.
