We look at the division of 723678 by 8 
Let's see how many times 8 fits into 723678.

Going ahead to step 1:
When dividing 7 by 8, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 8

Moving on to step 2:
If we divide 72 by 8, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 0 after subtracting 72 from 72.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 8

Going ahead to step 3:
When dividing 3 by 8, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 8

Step 4:
36 divided by 8 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 904.0
Subtract 32 from 36 to get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 8

Step 5:
8 can be fit into 47 5 times, resulting in a remainder of 7.
The next digit of our result is 5. 
Result so far: 9045.0
Deduct 40 from 47 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 8

On to step 6:
78 divided by 8 is 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 90459.0
If we subtract 72 from 78, 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.

Step 7:
When dividing 60 by 8, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 90459.7
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.

Going ahead to step 8:
8 goes into 40 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 90459.75
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 9:
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: 90459.75
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.

Step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 90459.75
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.

Our division results in 90459.75 with a remaining 0.0.
