Let's divide 543985 by 30
Let's see how many times 30 fits into 543985.

Let's proceed to step 1:
If we divide 5 by 30, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 30

Let's proceed to step 2:
30 goes into 54 1 times with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 30 from 54 to get 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 30

Advancing to step 3:
30 goes into 243 8 times with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 240 from 243 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 30

Moving on to step 4:
If we divide 39 by 30, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 181.0
Subtract 30 from 39 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 30

Moving on to step 5:
If we divide 98 by 30, we get 3 and a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 1813.0
If we subtract 90 from 98, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 30

Let's proceed to step 6:
The number 30 fits into 85 2 times, leaving a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 18132.0
The remainder is 25 after subtracting 60 from 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
When dividing 250 by 30, we get 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 18132.8
If we take 240 away from 250, 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.

Moving on to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 18132.83
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 18132.833
If we subtract 90 from 100, we get 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 18132.833 with a balance of 0.001.
