We look at the division of 858086 by 30 
We're looking to find how many times 30 goes into 858086.

Advancing to step 1:
30 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 30

Let's proceed to step 2:
30 goes into 85 2 times with a remainder of 25.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 60 from 85 leaves us with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 30

Going ahead to step 3:
When dividing 258 by 30, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtracting 240 from 258 leaves us with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 30

Moving on to step 4:
The number 30 fits into 180 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 286.0
Deduct 180 from 180 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 30

Let's proceed to step 5:
8 divided by 30 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 2860.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 30

Advancing to step 6:
30 can be fit into 86 2 times, resulting in a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 28602.0
Subtract 60 from 86 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
260 divided by 30 is 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 28602.8
Subtract 240 from 260 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.

Moving on to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 28602.86
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.

Going ahead to step 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 28602.866
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.

After the division, we end up with 28602.866 and a remainder of 0.002.
