We look at the division of 347966 by 12 
Our goal is to divide 347966 by 12.

Step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 12

Moving on to step 2:
12 can be fit into 34 2 times, resulting in a remainder of 10.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 24 from 34 and we're left with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 12

Step 3:
107 divided by 12 is 8 with a remainder of 11.
The next digit of our result is 8. 
Result so far: 28.0
If we subtract 96 from 107, we get 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 12

Moving on to step 4:
12 goes into 119 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 289.0
Subtracting 108 from 119 leaves us with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 12

Step 5:
12 goes into 116 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 2899.0
Deduct 108 from 116 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 12

Step 6:
When dividing 86 by 12, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 28997.0
Deduct 84 from 86 and we're left 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.

Advancing to step 7:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 28997.1
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 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 28997.16
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.

Moving on to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 28997.166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 28997.166 with a remaining 0.0008.
