We look at the division of 66780788 by 8 
We're looking to find how many times 8 goes into 66780788.

Moving on to step 1:
When dividing 6 by 8, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 8

Going ahead to step 2:
8 can be fit into 66 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 64 from 66 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 8

Going ahead to step 3:
8 can be fit into 27 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 83.0
Deduct 24 from 27 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 8

Going ahead to step 4:
The number 8 fits into 38 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 834.0
Deduct 32 from 38 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 8

Step 5:
8 goes into 60 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 8347.0
If we take 56 away from 60, we end up with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 8

Moving on to step 6:
47 divided by 8 is 5 with a remainder of 7.
The next digit of our result is 5. 
Result so far: 83475.0
Subtract 40 from 47 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 8

Step 7:
If we divide 78 by 8, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 834759.0
The remainder is 6 after subtracting 72 from 78.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 8

Step 8:
If we divide 68 by 8, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 8347598.0
Subtracting 64 from 68 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.

Moving on to step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8347598.5
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8347598.5
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.

Let's proceed to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8347598.5
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.

After the division, we end up with 8347598.5 and a remainder of 0.0.
