239549 ÷ 12 
Let's see how many times 12 fits into 239549.

Advancing to step 1:
2 divided by 12 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 12

Going ahead to step 2:
12 goes into 23 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 12 away from 23, we end up with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 12

Step 3:
12 goes into 119 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 108 from 119 leaves us with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 12

Moving on to step 4:
12 can be fit into 115 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 199.0
Subtracting 108 from 115 leaves us with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 12

On to step 5:
If we divide 74 by 12, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 1996.0
If we take 72 away from 74, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 12

Step 6:
12 goes into 29 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 19962.0
The remainder is 5 after subtracting 24 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
50 divided by 12 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 19962.4
Subtracting 48 from 50 leaves us 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.

Step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 19962.41
If we take 12 away from 20, we end up 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.

Let's proceed to step 9:
80 divided by 12 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 19962.416
Subtracting 72 from 80 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.

On to step 10:
12 goes into 80 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 19962.4166
Deduct 72 from 80 and we're left 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.

After the division, we end up with 19962.4166 and a remainder of 8e-05.
