We divide 620946 by 30
Our goal is to divide 620946 by 30.

On to step 1:
If we divide 6 by 30, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 30

Step 2:
30 can be fit into 62 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 60 away from 62, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 30

On to step 3:
If we divide 20 by 30, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 20 to get 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 30

Step 4:
209 divided by 30 is 6 with a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 206.0
Subtracting 180 from 209 leaves us with 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 30

Going ahead to step 5:
The number 30 fits into 294 9 times, leaving a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 2069.0
If we subtract 270 from 294, we get 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 30

Going ahead to step 6:
30 can be fit into 246 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 20698.0
Subtract 240 from 246 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
30 goes into 60 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 20698.2
If we take 60 away from 60, 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.

Let's proceed to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20698.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20698.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 20698.2 with a balance of 0.0.
