We're dividing 866739 by 30 
We want to figure out the number of times 866739 can be divided by 30.

Moving on to step 1:
8 divided by 30 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 30

Going ahead to step 2:
When dividing 86 by 30, we get 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 60 from 86, we get 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 30

Going ahead to step 3:
30 goes into 266 8 times with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 26 after subtracting 240 from 266.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 30

Step 4:
30 goes into 267 8 times with a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 288.0
The remainder is 27 after subtracting 240 from 267.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 30

Moving on to step 5:
If we divide 273 by 30, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 2889.0
If we take 270 away from 273, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 30

Moving on to step 6:
The number 30 fits into 39 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 28891.0
If we take 30 away from 39, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
90 divided by 30 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 28891.3
Subtract 90 from 90 to get 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 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28891.3
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.

Let's proceed to step 9:
30 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28891.3
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 28891.3 with a remaining 0.0.
