Let's divide 665880 by 79
Our goal is to divide 665880 by 79.

Step 1:
79 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 79

Advancing to step 2:
79 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 79

On to step 3:
79 can be fit into 665 8 times, resulting in a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 632 away from 665, we end up with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 79

Going ahead to step 4:
338 divided by 79 is 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtracting 316 from 338 leaves us with 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 79

Going ahead to step 5:
The number 79 fits into 228 2 times, leaving a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 842.0
If we take 158 away from 228, we end up with 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 79

On to step 6:
The number 79 fits into 700 8 times, leaving a remainder of 68.
The next digit of our result is 8. 
Result so far: 8428.0
The remainder is 68 after subtracting 632 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 7:
79 goes into 680 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 8428.8
Subtracting 632 from 680 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
The number 79 fits into 480 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 8428.86
The remainder is 6 after subtracting 474 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
60 divided by 79 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 8428.86
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
If we divide 600 by 79, we get 7 and a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 8428.8607
The remainder is 47 after subtracting 553 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 11:
79 goes into 470 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 8428.86075
Subtract 395 from 470 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
750 divided by 79 is 9 with a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 8428.860759
Subtracting 711 from 750 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 13:
390 divided by 79 is 4 with a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 8428.8607594
The remainder is 74 after subtracting 316 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 14:
79 goes into 740 9 times with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 8428.86075949
Subtracting 711 from 740 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 8428.86075949, with a leftover of 2.9e-08.
