648488 ÷ 30 
Let's see how many times 30 fits into 648488.

Going ahead to step 1:
When dividing 6 by 30, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 30

Moving on to step 2:
30 can be fit into 64 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 60 from 64 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 30

Step 3:
If we divide 48 by 30, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 30 from 48 leaves us with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 30

Advancing to step 4:
184 divided by 30 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 216.0
If we subtract 180 from 184, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 30

Step 5:
30 can be fit into 48 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 2161.0
Subtract 30 from 48 to get 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 30

Moving on to step 6:
When dividing 188 by 30, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 21616.0
Subtracting 180 from 188 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:
When dividing 80 by 30, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 21616.2
Deduct 60 from 80 and we're left 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.

On to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 21616.26
Subtract 180 from 200 to 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:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 21616.266
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.

The final result is 21616.266 with a remainder of 0.002.
