We divide 421400 by 30
Let's see how many times 30 fits into 421400.

Moving on to step 1:
When dividing 4 by 30, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 30

Let's proceed to step 2:
The number 30 fits into 42 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 12 after subtracting 30 from 42.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 30

Step 3:
30 goes into 121 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 120 away from 121, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 30

Moving on to step 4:
If we divide 14 by 30, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 30

Going ahead to step 5:
30 goes into 140 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 1404.0
Subtract 120 from 140 to get 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 30

Moving on to step 6:
200 divided by 30 is 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 14046.0
If we take 180 away from 200, we end up 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 7:
If we divide 200 by 30, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 14046.6
If we subtract 180 from 200, 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:
When dividing 200 by 30, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 14046.66
If we take 180 away from 200, we end up 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.

In conclusion, the division gives 14046.66 with a balance of 0.02.
