Let's divide 642135 by 30
Let's see how many times 30 fits into 642135.

Going ahead to step 1:
The number 30 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 30

Advancing to step 2:
When dividing 64 by 30, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 60 from 64 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 30

On to step 3:
When dividing 42 by 30, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 12 after subtracting 30 from 42.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 30

On to step 4:
The number 30 fits into 121 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 214.0
The remainder is 1 after subtracting 120 from 121.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 30

Let's proceed to step 5:
30 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 2140.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 30

Going ahead to step 6:
The number 30 fits into 135 4 times, leaving a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 21404.0
If we take 120 away from 135, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
If we divide 150 by 30, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 21404.5
If we subtract 150 from 150, 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.

Let's proceed to step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21404.5
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.

Advancing to step 9:
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: 21404.5
Deduct 0 from 0 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.

In conclusion, the division gives 21404.5 with a balance of 0.0.
