39188112 ÷ 12 
We're looking to find how many times 12 goes into 39188112.

Step 1:
When dividing 3 by 12, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 12

Moving on to step 2:
12 goes into 39 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 36 from 39, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 12

Let's proceed to step 3:
When dividing 31 by 12, we get 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we subtract 24 from 31, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 12

On to step 4:
12 goes into 78 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 326.0
If we subtract 72 from 78, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 12

Step 5:
12 can be fit into 68 5 times, resulting in a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 3265.0
The remainder is 8 after subtracting 60 from 68.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 12

On to step 6:
12 goes into 81 6 times with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 32656.0
Deduct 72 from 81 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 12

Advancing to step 7:
12 can be fit into 91 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 326567.0
Subtracting 84 from 91 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 12

Let's proceed to step 8:
The number 12 fits into 72 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 3265676.0
Deduct 72 from 72 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.

Going ahead to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 3265676.0
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.

On to step 10:
12 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3265676.0
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 3265676.0 and a remainder of 0.0.
