864386 ÷ 30 
We want to figure out the number of times 864386 can be divided by 30.

Step 1:
The number 30 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 30

Going ahead to step 2:
30 can be fit into 86 2 times, resulting in a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 60 away from 86, we end up with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 30

Moving on to step 3:
If we divide 264 by 30, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 240 away from 264, we end up with 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 30

Going ahead to step 4:
The number 30 fits into 243 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 288.0
Subtracting 240 from 243 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 30

Let's proceed to step 5:
30 can be fit into 38 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 2881.0
If we take 30 away from 38, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 30

Going ahead to step 6:
The number 30 fits into 86 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 28812.0
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.

Advancing to step 7:
260 divided by 30 is 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 28812.8
If we take 240 away from 260, we end up 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.

Step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 28812.86
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.

Let's proceed to step 9:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 28812.866
Subtract 180 from 200 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.

In conclusion, the division gives 28812.866 with a balance of 0.002.
