We divide 342495 by 12
Our goal is to divide 342495 by 12.

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
Subtracting 0 from 3 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 12

Moving on to step 2:
12 goes into 34 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 24 from 34 leaves us with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 12

Step 3:
When dividing 102 by 12, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 28.0
If we subtract 96 from 102, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 12

Let's proceed to step 4:
12 goes into 64 5 times with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 285.0
Subtracting 60 from 64 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 12

Let's proceed to step 5:
When dividing 49 by 12, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 2854.0
Subtracting 48 from 49 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 12

On to step 6:
If we divide 15 by 12, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 28541.0
If we subtract 12 from 15, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
If we divide 30 by 12, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 28541.2
Deduct 24 from 30 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 28541.25
If we subtract 60 from 60, 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.

Advancing to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28541.25
Subtract 0 from 0 to 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 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28541.25
If we take 0 away from 0, we end up 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.

Our division results in 28541.25 with a remaining 0.0.
