108400 divided by 12 
We want to figure out the number of times 108400 can be divided by 12.

Moving on to step 1:
If we divide 1 by 12, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 12

Moving on to step 2:
10 divided by 12 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 12

Step 3:
12 can be fit into 108 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 108 away from 108, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 12

Going ahead to step 4:
When dividing 4 by 12, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 12

Moving on to step 5:
If we divide 40 by 12, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 903.0
If we take 36 away from 40, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 12

Moving on to step 6:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 9033.0
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 12 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 9033.3
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 9033.33
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 9033.33 with a balance of 0.004.
