We're dividing 539660 by 30 
We want to figure out the number of times 539660 can be divided by 30.

Let's proceed to step 1:
30 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 30

Moving on to step 2:
If we divide 53 by 30, we get 1 and a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 30 from 53, we get 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 30

Step 3:
The number 30 fits into 239 7 times, leaving a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 210 from 239 leaves us with 29.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 30

Going ahead to step 4:
The number 30 fits into 296 9 times, leaving a remainder of 26.
The next digit of our result is 9. 
Result so far: 179.0
The remainder is 26 after subtracting 270 from 296.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 30

Step 5:
When dividing 266 by 30, we get 8 with a remainder of 26.
The next digit of our result is 8. 
Result so far: 1798.0
Subtract 240 from 266 to get 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 30

Moving on to step 6:
30 can be fit into 260 8 times, resulting in a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 17988.0
If we subtract 240 from 260, 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.

Let's proceed to step 7:
30 goes into 200 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 17988.6
Deduct 180 from 200 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.

Going ahead to step 8:
30 goes into 200 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 17988.66
Deduct 180 from 200 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.

Our division results in 17988.66 with a remaining 0.02.
