Let's divide 686663 by 8
We want to figure out the number of times 686663 can be divided by 8.

Let's proceed to step 1:
The number 8 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 8

On to step 2:
8 can be fit into 68 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 64 from 68 to get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 8

Step 3:
The number 8 fits into 46 5 times, leaving a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Deduct 40 from 46 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 8

Advancing to step 4:
When dividing 66 by 8, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 858.0
The remainder is 2 after subtracting 64 from 66.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 8

Step 5:
When dividing 26 by 8, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 8583.0
Deduct 24 from 26 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 8

Step 6:
The number 8 fits into 23 2 times, leaving a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 85832.0
Subtract 16 from 23 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
70 divided by 8 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 85832.8
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.

Step 8:
When dividing 60 by 8, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 85832.87
Subtracting 56 from 60 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.

Step 9:
When dividing 40 by 8, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 85832.875
Subtracting 40 from 40 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.

Going ahead to step 10:
8 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 85832.875
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.

On to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 85832.875
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.

The final outcome is 85832.875, with a leftover of 0.0.
