We look at the division of 66799 by 79 
We want to divide 66799 by 79.

Going ahead to step 1:
The number 79 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 79

Advancing to step 2:
79 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 79

Moving on to step 3:
The number 79 fits into 667 8 times, leaving a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 632 from 667 leaves us with 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 79

Advancing to step 4:
79 can be fit into 359 4 times, resulting in a remainder of 43.
The next digit of our result is 4. 
Result so far: 84.0
The remainder is 43 after subtracting 316 from 359.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 79

Step 5:
If we divide 439 by 79, we get 5 and a remainder of 44.
Write down 5 as next digit of the result. 
Result so far: 845.0
The remainder is 44 after subtracting 395 from 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 6:
79 can be fit into 440 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 845.5
The remainder is 45 after subtracting 395 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
The number 79 fits into 450 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 845.55
Subtract 395 from 450 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 845.55 with a remaining 0.055.
