We look at the division of 866772 by 30 
We're looking to find how many times 30 goes into 866772.

On to step 1:
When dividing 8 by 30, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 30

Moving on to step 2:
When dividing 86 by 30, we get 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 26 after subtracting 60 from 86.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 30

On to step 3:
When dividing 266 by 30, we get 8 with a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 240 from 266 leaves us with 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 30

Let's proceed to step 4:
If we divide 267 by 30, we get 8 and a remainder of 27.
The next digit of our result is 8. 
Result so far: 288.0
The remainder is 27 after subtracting 240 from 267.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 30

Let's proceed to step 5:
30 goes into 277 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 2889.0
Subtract 270 from 277 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 30

Going ahead to step 6:
If we divide 72 by 30, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 28892.0
Deduct 60 from 72 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
120 divided by 30 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 28892.4
Subtracting 120 from 120 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.

Step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28892.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28892.4
Deduct 0 from 0 and we're left 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.

The final outcome is 28892.4, with a leftover of 0.0.
