Let's divide 666291 by 8
Our goal is to divide 666291 by 8.

On to step 1:
8 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 8

Let's proceed to step 2:
8 can be fit into 66 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 64 from 66, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 8

Advancing to step 3:
The number 8 fits into 26 3 times, leaving a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 24 from 26 and we're left with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 8

Moving on to step 4:
22 divided by 8 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 832.0
If we take 16 away from 22, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 8

Step 5:
The number 8 fits into 69 8 times, leaving a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 8328.0
If we subtract 64 from 69, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 8

Advancing to step 6:
8 goes into 51 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 83286.0
Subtract 48 from 51 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
30 divided by 8 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 83286.3
If we subtract 24 from 30, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
60 divided by 8 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 83286.37
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
When dividing 40 by 8, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 83286.375
If we subtract 40 from 40, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 83286.375
Subtracting 0 from 0 leaves us 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.

On to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 83286.375
If we take 0 away from 0, 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.

Our division results in 83286.375 with a remaining 0.0.
