66033239 ÷ 666 
Our goal is to divide 66033239 by 666.

On to step 1:
The number 666 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 666

Going ahead to step 2:
666 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.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 666

Advancing to step 3:
If we divide 660 by 666, we get 0 and a remainder of 660.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 660 after subtracting 0 from 660.
Include the next digit (3) from the dividend after 660, then repeat: 6603 / 666

On to step 4:
666 goes into 6603 9 times with a remainder of 609.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 5994 from 6603 and we're left with 609.
Bring next digit (3) of the dividend behind the 609 and repeat the process: 6093 / 666

On to step 5:
6093 divided by 666 is 9 with a remainder of 99.
The next digit of our result is 9. 
Result so far: 99.0
If we subtract 5994 from 6093, we get 99.
Take the next digit (2) from the dividend and append it to 99, then repeat: 992 / 666

Going ahead to step 6:
992 divided by 666 is 1 with a remainder of 326.
Put 1 as the next digit of the answer. 
Result so far: 991.0
Subtracting 666 from 992 leaves us with 326.
Fetch the next digit (3) from the dividend, attach it to 326 and continue: 3263 / 666

On to step 7:
666 goes into 3263 4 times with a remainder of 599.
Write down 4 as next digit of the result. 
Result so far: 9914.0
Deduct 2664 from 3263 and we're left with 599.
Include the next digit (9) from the dividend after 599, then repeat: 5999 / 666

Moving on to step 8:
If we divide 5999 by 666, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 99149.0
The remainder is 5 after subtracting 5994 from 5999.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
If we divide 50 by 666, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 99149.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
The number 666 fits into 500 0 times, leaving a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 99149.0
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 99149.0 with a remaining 0.5.
