We're dividing 636647 by 8 
We want to figure out the number of times 636647 can be divided by 8.

On to step 1:
6 divided by 8 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 8

On to step 2:
If we divide 63 by 8, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 56 away from 63, we end up with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 8

Going ahead to step 3:
When dividing 76 by 8, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtracting 72 from 76 leaves us with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 8

Step 4:
The number 8 fits into 46 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 795.0
The remainder is 6 after subtracting 40 from 46.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 8

Let's proceed to step 5:
When dividing 64 by 8, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 7958.0
If we take 64 away from 64, we end up 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.
Put 0 as the next digit of the answer. 
Result so far: 79580.0
Subtract 0 from 7 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.

Moving on to step 7:
8 can be fit into 70 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 79580.8
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:
8 can be fit into 60 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 79580.87
Deduct 56 from 60 and we're left 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.

On to step 9:
The number 8 fits into 40 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 79580.875
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:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 79580.875
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.

Step 11:
8 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 79580.875
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.

In conclusion, the division gives 79580.875 with a balance of 0.0.
