We look at the division of 579642 by 30 
Our goal is to divide 579642 by 30.

On to step 1:
The number 30 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 30

Advancing to step 2:
30 goes into 57 1 times with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 27 after subtracting 30 from 57.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 30

On to step 3:
30 can be fit into 279 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 270 from 279, we get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 30

Going ahead to step 4:
30 can be fit into 96 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 193.0
If we subtract 90 from 96, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 30

Going ahead to step 5:
30 goes into 64 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 1932.0
The remainder is 4 after subtracting 60 from 64.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 30

Step 6:
When dividing 42 by 30, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 19321.0
Subtract 30 from 42 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
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: 19321.4
Deduct 120 from 120 and we're left 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.

On to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19321.4
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.

Advancing to step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19321.4
If we subtract 0 from 0, we get 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 19321.4 with a balance of 0.0.
