We look at the division of 868546 by 30 
We're looking to find how many times 30 goes into 868546.

Step 1:
When dividing 8 by 30, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 30

Let's proceed to step 2:
The number 30 fits into 86 2 times, leaving a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 60 from 86 and we're left with 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 30

Let's proceed to step 3:
If we divide 268 by 30, we get 8 and a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 240 from 268, we get 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 30

On to step 4:
30 goes into 285 9 times with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 289.0
If we subtract 270 from 285, we get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 30

Moving on to step 5:
30 goes into 154 5 times with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 2895.0
If we subtract 150 from 154, we get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 30

Step 6:
When dividing 46 by 30, we get 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 28951.0
Deduct 30 from 46 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
If we divide 160 by 30, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 28951.5
Subtract 150 from 160 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 28951.53
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 28951.533
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 28951.533 with a remaining 0.001.
