Let's divide 668900 by 8
We're looking to find how many times 8 goes into 668900.

Let's proceed to step 1:
8 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 8

Step 2:
66 divided by 8 is 8 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 (8) of the dividend behind the 2 and repeat the process: 28 / 8

Step 3:
8 goes into 28 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
Subtracting 24 from 28 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 8

Let's proceed to step 4:
When dividing 49 by 8, we get 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 836.0
If we take 48 away from 49, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 8

Advancing to step 5:
The number 8 fits into 10 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 8361.0
The remainder is 2 after subtracting 8 from 10.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 8

Advancing to step 6:
20 divided by 8 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 83612.0
Subtracting 16 from 20 leaves us 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.

Going ahead to step 7:
If we divide 40 by 8, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 83612.5
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.

Advancing to step 8:
If we divide 0 by 8, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 83612.5
If we subtract 0 from 0, 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.

Let's proceed to step 9:
When dividing 0 by 8, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 83612.5
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 83612.5 with a remaining 0.0.
