We look at the division of 216420 by 30 
Let's see how many times 30 fits into 216420.

Advancing to step 1:
The number 30 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 30

Step 2:
When dividing 21 by 30, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 30

Going ahead to step 3:
216 divided by 30 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 6 after subtracting 210 from 216.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 30

On to step 4:
64 divided by 30 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Deduct 60 from 64 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 30

Step 5:
30 goes into 42 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 721.0
If we take 30 away from 42, we end up with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 30

Step 6:
If we divide 120 by 30, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 7214.0
If we take 120 away from 120, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 7214.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 7214.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 7214.0 with a remainder of 0.0.
