12864684 divided by 30 
Our goal is to divide 12864684 by 30.

Let's proceed to step 1:
30 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 30

Moving on to step 2:
The number 30 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 30

Advancing to step 3:
If we divide 128 by 30, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 120 away from 128, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 30

Step 4:
30 goes into 86 2 times with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we subtract 60 from 86, we get 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 30

On to step 5:
30 goes into 264 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 428.0
If we subtract 240 from 264, we get 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 30

Going ahead to step 6:
30 goes into 246 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 4288.0
Subtract 240 from 246 to get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 30

Moving on to step 7:
30 goes into 68 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 42882.0
Subtracting 60 from 68 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 30

Let's proceed to step 8:
The number 30 fits into 84 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 428822.0
Subtract 60 from 84 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
If we divide 240 by 30, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 428822.8
Subtract 240 from 240 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 10:
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: 428822.8
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.

Step 11:
0 divided by 30 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 428822.8
Subtracting 0 from 0 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.

After the division, we end up with 428822.8 and a remainder of 0.0.
