We look at the division of 19784 by 12 
Let's see how many times 12 fits into 19784.

On to step 1:
12 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 12

Step 2:
The number 12 fits into 19 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 12 from 19 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 12

Step 3:
12 goes into 77 6 times with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 72 from 77 to get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 12

Moving on to step 4:
12 goes into 58 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 164.0
Deduct 48 from 58 and we're left with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 12

Let's proceed to step 5:
When dividing 104 by 12, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 1648.0
Deduct 96 from 104 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.

Going ahead to step 6:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 1648.6
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.

On to step 7:
If we divide 80 by 12, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1648.66
Subtract 72 from 80 to 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 outcome is 1648.66, with a leftover of 0.008.
