We're dividing 858353 by 30 
Let's see how many times 30 fits into 858353.

On to step 1:
30 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 30

Step 2:
If we divide 85 by 30, we get 2 and a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 60 away from 85, we end up with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 30

Going ahead to step 3:
30 can be fit into 258 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 240 from 258, we get 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 30

Step 4:
The number 30 fits into 183 6 times, leaving a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 286.0
Deduct 180 from 183 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 30

Let's proceed to step 5:
30 goes into 35 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 2861.0
Subtract 30 from 35 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 30

Going ahead to step 6:
30 goes into 53 1 times with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 28611.0
Subtracting 30 from 53 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
If we divide 230 by 30, we get 7 and a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 28611.7
If we subtract 210 from 230, 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.

Advancing to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 28611.76
Deduct 180 from 200 and we're left 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:
30 goes into 200 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 28611.766
Subtracting 180 from 200 leaves us 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.

The final result is 28611.766 with a remainder of 0.002.
