We look at the division of 686508 by 30 
We want to figure out the number of times 686508 can be divided by 30.

Going ahead to step 1:
6 divided by 30 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 30

On to step 2:
68 divided by 30 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 60 away from 68, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 30

On to step 3:
30 can be fit into 86 2 times, resulting in a remainder of 26.
The next digit of our result is 2. 
Result so far: 22.0
If we take 60 away from 86, we end up with 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 30

Let's proceed to step 4:
If we divide 265 by 30, we get 8 and a remainder of 25.
The next digit of our result is 8. 
Result so far: 228.0
Subtract 240 from 265 to get 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 30

On to step 5:
30 can be fit into 250 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 2288.0
Subtract 240 from 250 to get 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 30

Let's proceed to step 6:
108 divided by 30 is 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 22883.0
If we subtract 90 from 108, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
The number 30 fits into 180 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 22883.6
If we take 180 away from 180, 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.

Step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 22883.6
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.

Going ahead to step 9:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22883.6
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 22883.6 with a balance of 0.0.
