342011 ÷ 12 
Our goal is to divide 342011 by 12.

Going ahead to step 1:
The number 12 fits into 3 0 times, leaving 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.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 12

On to step 2:
When dividing 34 by 12, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 24 from 34 to get 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 12

Going ahead to 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.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 12

Let's proceed to step 4:
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: 285.0
Subtract 60 from 60 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 12

On to step 5:
1 divided by 12 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 2850.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 12

On to step 6:
When dividing 11 by 12, we get 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 28500.0
If we subtract 0 from 11, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 12 fits into 110 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 28500.9
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to 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: 28500.91
If we subtract 12 from 20, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 28500.916
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.

Step 10:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 28500.9166
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.

The quotient of the division is 28500.9166, and the remainder is 8e-05.
