855489 ÷ 30 
We want to divide 855489 by 30.

Step 1:
30 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 30

Step 2:
If we divide 85 by 30, we get 2 and a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 25 after subtracting 60 from 85.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 30

Let's proceed to step 3:
When dividing 255 by 30, we get 8 with a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 240 from 255, we get 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 30

Advancing to step 4:
30 can be fit into 154 5 times, resulting in a remainder of 4.
The next digit of our result is 5. 
Result so far: 285.0
The remainder is 4 after subtracting 150 from 154.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 30

On to step 5:
If we divide 48 by 30, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 2851.0
If we take 30 away from 48, we end up with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 30

On to step 6:
30 goes into 189 6 times with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 28516.0
The remainder is 9 after subtracting 180 from 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
When dividing 90 by 30, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 28516.3
Subtract 90 from 90 to 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.

Step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28516.3
Subtract 0 from 0 to 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.

On to step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 28516.3
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 28516.3 and a remainder of 0.0.
