191831 divided by 12 
We want to divide 191831 by 12.

Moving on to step 1:
1 divided by 12 is 0 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.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 12

On to step 2:
When dividing 19 by 12, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 12 from 19 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 12

Let's proceed to step 3:
71 divided by 12 is 5 with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 60 from 71 and we're left with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 12

Going ahead to step 4:
When dividing 118 by 12, we get 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
If we take 108 away from 118, we end up with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 12

Let's proceed to step 5:
When dividing 103 by 12, we get 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 1598.0
Subtract 96 from 103 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 12

Moving on to step 6:
12 goes into 71 5 times with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 15985.0
If we take 60 away from 71, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
12 goes into 110 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 15985.9
Deduct 108 from 110 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.

Let's proceed to step 8:
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: 15985.91
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 15985.916
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.

Let's proceed to step 10:
If we divide 80 by 12, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 15985.9166
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.

After the division, we end up with 15985.9166 and a remainder of 8e-05.
