392124 divided by 12 
We're looking to find how many times 12 goes into 392124.

Let's proceed to step 1:
3 divided by 12 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 12

Going ahead to step 2:
The number 12 fits into 39 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 36 from 39, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 12

Let's proceed to step 3:
12 goes into 32 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 32.0
If we subtract 24 from 32, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 12

Let's proceed to step 4:
If we divide 81 by 12, we get 6 and a remainder of 9.
The next digit of our result is 6. 
Result so far: 326.0
Subtract 72 from 81 to get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 12

Step 5:
12 goes into 92 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 3267.0
Deduct 84 from 92 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 12

Let's proceed to step 6:
12 can be fit into 84 7 times, resulting in a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 32677.0
If we subtract 84 from 84, 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.

On to step 7:
When dividing 0 by 12, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 32677.0
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.

Step 8:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 32677.0
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.

In conclusion, the division gives 32677.0 with a balance of 0.0.
