Let's divide 191836 by 12
We want to figure out the number of times 191836 can be divided by 12.

Step 1:
12 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 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.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 12 from 19, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 12

Let's proceed to step 3:
The number 12 fits into 71 5 times, leaving a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 60 from 71 to get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 12

On to step 4:
12 goes into 118 9 times with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Deduct 108 from 118 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 12

Going ahead to step 5:
12 goes into 103 8 times with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 1598.0
The remainder is 7 after subtracting 96 from 103.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 12

On to step 6:
When dividing 76 by 12, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 15986.0
Subtracting 72 from 76 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.

Advancing to step 7:
12 goes into 40 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 15986.3
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.

Advancing to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 15986.33
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.

After the division, we end up with 15986.33 and a remainder of 0.004.
