Let's divide 305985 by 30
We're looking to find how many times 30 goes into 305985.

Advancing to step 1:
3 divided by 30 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 30

Let's proceed to step 2:
30 can be fit into 30 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 30 from 30 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 30

Going ahead to step 3:
5 divided by 30 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 5 to get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 30

Let's proceed to step 4:
If we divide 59 by 30, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtracting 30 from 59 leaves us with 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 30

Advancing to step 5:
30 goes into 298 9 times with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 1019.0
If we subtract 270 from 298, we get 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 30

Going ahead to step 6:
When dividing 285 by 30, we get 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 10199.0
Subtracting 270 from 285 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
If we divide 150 by 30, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10199.5
If we subtract 150 from 150, 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 8:
If we divide 0 by 30, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10199.5
Deduct 0 from 0 and we're left 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.

Going ahead to step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10199.5
Deduct 0 from 0 and we're left 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.

Our division results in 10199.5 with a remaining 0.0.
