We're dividing 515668 by 30 
Let's see how many times 30 fits into 515668.

Going ahead to step 1:
5 divided by 30 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 30

On to step 2:
The number 30 fits into 51 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 30 from 51 to get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 30

Going ahead to step 3:
When dividing 215 by 30, we get 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 5 after subtracting 210 from 215.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 30

Moving on to step 4:
The number 30 fits into 56 1 times, leaving a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Subtracting 30 from 56 leaves us with 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 30

Going ahead to step 5:
30 can be fit into 266 8 times, resulting in a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 1718.0
Subtract 240 from 266 to get 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 30

Let's proceed to step 6:
When dividing 268 by 30, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 17188.0
If we take 240 away from 268, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
30 can be fit into 280 9 times, resulting in a remainder of 10.
The next digit of our result is 9. 
Result so far: 17188.9
If we take 270 away from 280, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
100 divided by 30 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 17188.93
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 17188.933
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 17188.933 with a balance of 0.001.
