We look at the division of 57582286 by 666 
Let's see how many times 666 fits into 57582286.

On to step 1:
5 divided by 666 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 666

Moving on to step 2:
If we divide 57 by 666, we get 0 and a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 666

Going ahead to step 3:
666 goes into 575 0 times with a remainder of 575.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 575 to get 575.
Take the next digit (8) from the dividend and append it to 575, then repeat: 5758 / 666

Going ahead to step 4:
The number 666 fits into 5758 8 times, leaving a remainder of 430.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 430 after subtracting 5328 from 5758.
Grab the next digit (2) from the dividend, add it to 430, then carry on: 4302 / 666

Going ahead to step 5:
666 can be fit into 4302 6 times, resulting in a remainder of 306.
Write down 6 as next digit of the result. 
Result so far: 86.0
Deduct 3996 from 4302 and we're left with 306.
Append the next digit (2) from the dividend to 306 and continue with: 3062 / 666

Advancing to step 6:
666 goes into 3062 4 times with a remainder of 398.
Use 4 as the next digit of our solution. 
Result so far: 864.0
If we subtract 2664 from 3062, we get 398.
Include the next digit (8) from the dividend after 398, then repeat: 3988 / 666

Moving on to step 7:
3988 divided by 666 is 5 with a remainder of 658.
The number 5 becomes the next digit in our result. 
Result so far: 8645.0
Subtract 3330 from 3988 to get 658.
Bring next digit (6) of the dividend behind the 658 and repeat the process: 6586 / 666

Going ahead to step 8:
If we divide 6586 by 666, we get 9 and a remainder of 592.
Put 9 as the next digit of the answer. 
Result so far: 86459.0
If we subtract 5994 from 6586, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Let's proceed to step 9:
If we divide 5920 by 666, we get 8 and a remainder of 592.
The next digit of our result is 8. 
Result so far: 86459.8
Subtracting 5328 from 5920 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Advancing to step 10:
666 goes into 5920 8 times with a remainder of 592.
Record the quotient 8 as the next digit in the result. 
Result so far: 86459.88
The remainder is 592 after subtracting 5328 from 5920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

After the division, we end up with 86459.88 and a remainder of 0.592.
