We look at the division of 666659 by 8 
We're looking to find how many times 8 goes into 666659.

Step 1:
The number 8 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 8

Let's proceed to step 2:
8 goes into 66 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 64 from 66 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 8

On to step 3:
8 can be fit into 26 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtract 24 from 26 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 8

On to step 4:
8 goes into 26 3 times with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 833.0
If we take 24 away from 26, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 8

Advancing to step 5:
8 can be fit into 25 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 8333.0
The remainder is 1 after subtracting 24 from 25.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 8

Going ahead to step 6:
The number 8 fits into 19 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 83332.0
Subtracting 16 from 19 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 8, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 83332.3
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.

On to step 8:
8 can be fit into 60 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 83332.37
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 8 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 83332.375
If we take 40 away from 40, 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.

Let's proceed to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 83332.375
The remainder is 0 after subtracting 0 from 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 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 83332.375
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.

The final result is 83332.375 with a remainder of 0.0.
