Let's divide 879666 by 75
Let's see how many times 75 fits into 879666.

Going ahead to step 1:
The number 75 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 75

Let's proceed to step 2:
75 goes into 87 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 75 away from 87, we end up with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 75

Step 3:
129 divided by 75 is 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 75 from 129 and we're left with 54.
Append the next digit (6) from the dividend to 54 and continue with: 546 / 75

Step 4:
The number 75 fits into 546 7 times, leaving a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 117.0
The remainder is 21 after subtracting 525 from 546.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 75

Advancing to step 5:
216 divided by 75 is 2 with a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 1172.0
If we take 150 away from 216, we end up with 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 75

On to step 6:
666 divided by 75 is 8 with a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 11728.0
If we take 600 away from 666, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 7:
660 divided by 75 is 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 11728.8
The remainder is 60 after subtracting 600 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
75 can be fit into 600 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 11728.88
If we take 600 away from 600, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 11728.88, with a leftover of 0.0.
