285290 ÷ 30 
We want to figure out the number of times 285290 can be divided by 30.

Advancing to step 1:
30 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 30

Let's proceed to step 2:
If we divide 28 by 30, we get 0 and a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 30

Advancing to step 3:
If we divide 285 by 30, we get 9 and a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 270 away from 285, we end up with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 30

Moving on to step 4:
30 goes into 152 5 times with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we subtract 150 from 152, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 30

Advancing to step 5:
If we divide 29 by 30, we get 0 and a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 950.0
Deduct 0 from 29 and we're left with 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 30

On to step 6:
30 can be fit into 290 9 times, resulting in a remainder of 20.
The next digit of our result is 9. 
Result so far: 9509.0
If we take 270 away from 290, we end up 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 7:
If we divide 200 by 30, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 9509.6
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 9509.66
If we subtract 180 from 200, 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.

Our division results in 9509.66 with a remaining 0.02.
