We're dividing 609308 by 30 
We want to figure out the number of times 609308 can be divided by 30.

Going ahead to step 1:
30 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 30

Let's proceed to step 2:
The number 30 fits into 60 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 60 from 60 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 30

Step 3:
30 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 30

Advancing to step 4:
30 goes into 93 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 203.0
Subtract 90 from 93 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 30

On to step 5:
30 can be fit into 30 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 2031.0
If we subtract 30 from 30, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 30

Advancing to step 6:
When dividing 8 by 30, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 20310.0
Subtracting 0 from 8 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
The number 30 fits into 80 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 20310.2
If we take 60 away from 80, 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.

Step 8:
200 divided by 30 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 20310.26
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.

On to step 9:
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: 20310.266
Subtracting 180 from 200 leaves us 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.

The final result is 20310.266 with a remainder of 0.002.
