668887 ÷ 8 
We're looking to find how many times 8 goes into 668887.

Step 1:
8 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 8

Moving on to step 2:
The number 8 fits into 66 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 64 away from 66, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 8

On to step 3:
8 can be fit into 28 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we take 24 away from 28, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 8

On to step 4:
48 divided by 8 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 836.0
Subtract 48 from 48 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 8

Step 5:
8 divided by 8 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 8361.0
Subtracting 8 from 8 leaves us with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 8

Step 6:
8 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 83610.0
Deduct 0 from 7 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 8, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 83610.8
Subtracting 64 from 70 leaves us with 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:
8 goes into 60 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 83610.87
If we take 56 away from 60, we end up 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.

Moving on to step 9:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 83610.875
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.

Moving on to step 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 83610.875
Subtract 0 from 0 to 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.

Advancing to step 11:
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: 83610.875
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.

The quotient of the division is 83610.875, and the remainder is 0.0.
