We look at the division of 830780 by 12 
We want to figure out the number of times 830780 can be divided by 12.

Step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 12

Going ahead to step 2:
If we divide 83 by 12, we get 6 and a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 72 from 83, we get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 12

On to step 3:
12 goes into 110 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
The remainder is 2 after subtracting 108 from 110.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 12

Going ahead to step 4:
If we divide 27 by 12, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 692.0
The remainder is 3 after subtracting 24 from 27.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 12

Step 5:
If we divide 38 by 12, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 6923.0
Subtracting 36 from 38 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 12

Going ahead to step 6:
20 divided by 12 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 69231.0
If we subtract 12 from 20, 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 7:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 69231.6
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.

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: 69231.66
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.

The final outcome is 69231.66, with a leftover of 0.008.
