We're dividing 855122 by 30 
Let's see how many times 30 fits into 855122.

Going ahead to step 1:
The number 30 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 30

Let's proceed to step 2:
If we divide 85 by 30, we get 2 and a remainder of 25.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 60 from 85, we get 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 30

Going ahead to step 3:
30 can be fit into 255 8 times, resulting in a remainder of 15.
The next digit of our result is 8. 
Result so far: 28.0
Subtracting 240 from 255 leaves us with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 30

Moving on to step 4:
30 can be fit into 151 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 285.0
The remainder is 1 after subtracting 150 from 151.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 30

Step 5:
12 divided by 30 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 2850.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 30

Step 6:
30 goes into 122 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 28504.0
If we take 120 away from 122, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
30 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 28504.0
The remainder is 20 after subtracting 0 from 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 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 28504.06
If we take 180 away from 200, 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.

Advancing to step 9:
The number 30 fits into 200 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 28504.066
Subtract 180 from 200 to 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 28504.066 with a remaining 0.002.
