We look at the division of 791978 by 66 
We're looking to find how many times 66 goes into 791978.

Advancing to step 1:
7 divided by 66 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 66

Going ahead to step 2:
66 goes into 79 1 times with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 66 from 79 leaves us with 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 66

Moving on to step 3:
131 divided by 66 is 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 66 from 131, we get 65.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 66

Advancing to step 4:
66 goes into 659 9 times with a remainder of 65.
The next digit of our result is 9. 
Result so far: 119.0
If we take 594 away from 659, we end up with 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 66

Let's proceed to step 5:
The number 66 fits into 657 9 times, leaving a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 1199.0
Subtracting 594 from 657 leaves us with 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 66

Moving on to step 6:
If we divide 638 by 66, we get 9 and a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 11999.0
Deduct 594 from 638 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
The number 66 fits into 440 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 11999.6
Subtracting 396 from 440 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
66 can be fit into 440 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 11999.66
Subtracting 396 from 440 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 11999.66 with a balance of 0.044.
