191674 ÷ 12 
We want to divide 191674 by 12.

Step 1:
12 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 12

Step 2:
12 can be fit into 19 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 12 from 19, we get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 12

Step 3:
The number 12 fits into 71 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 60 from 71 leaves us with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 12

Let's proceed to step 4:
12 goes into 116 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 159.0
Subtract 108 from 116 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 12

Let's proceed to step 5:
12 goes into 87 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 1597.0
If we take 84 away from 87, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 12

Moving on to step 6:
When dividing 34 by 12, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 15972.0
Subtract 24 from 34 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 15972.8
Subtracting 96 from 100 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.

Step 8:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 15972.83
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.

On to step 9:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 15972.833
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.

Our division results in 15972.833 with a remaining 0.0004.
