We divide 339230 by 12
Our goal is to divide 339230 by 12.

Let's proceed to step 1:
12 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 12

Going ahead to step 2:
12 goes into 33 2 times with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 24 from 33 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 12

Advancing to step 3:
99 divided by 12 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 96 away from 99, we end up with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 12

Moving on to step 4:
12 goes into 32 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 282.0
If we subtract 24 from 32, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 12

Step 5:
The number 12 fits into 83 6 times, leaving a remainder of 11.
The next digit of our result is 6. 
Result so far: 2826.0
Subtract 72 from 83 to get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 12

Going ahead to step 6:
110 divided by 12 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 28269.0
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
12 can be fit into 20 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 28269.1
Subtracting 12 from 20 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 28269.16
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 28269.166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 28269.166 with a remaining 0.0008.
