342179 divided by 12 
We're looking to find how many times 12 goes into 342179.

On 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
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 12

Moving on to step 2:
If we divide 34 by 12, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 24 away from 34, we end up with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 12

Step 3:
If we divide 102 by 12, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we take 96 away from 102, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 12

Advancing to step 4:
12 goes into 61 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 285.0
Deduct 60 from 61 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 12

Step 5:
12 can be fit into 17 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 2851.0
Subtracting 12 from 17 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 12

On to step 6:
The number 12 fits into 59 4 times, leaving a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 28514.0
If we subtract 48 from 59, 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.

Step 7:
110 divided by 12 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 28514.9
If we take 108 away from 110, we end up with 2.
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:
20 divided by 12 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 28514.91
If we take 12 away from 20, we end up 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.

Going ahead to step 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 28514.916
Subtracting 72 from 80 leaves us 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.

Advancing to 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: 28514.9166
If we subtract 72 from 80, 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.

The final result is 28514.9166 with a remainder of 8e-05.
