638505 ÷ 8 
We're looking to find how many times 8 goes into 638505.

On 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
Subtracting 0 from 6 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 8

Going ahead to step 2:
8 can be fit into 63 7 times, resulting in 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.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 8

On to step 3:
When dividing 78 by 8, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
If we take 72 away from 78, we end up with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 8

On to step 4:
The number 8 fits into 65 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 798.0
Subtract 64 from 65 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 8

Moving on 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: 7981.0
Subtract 8 from 10 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 8

On to step 6:
25 divided by 8 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 79813.0
If we subtract 24 from 25, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
8 can be fit into 10 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 79813.1
If we subtract 8 from 10, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
20 divided by 8 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 79813.12
Subtract 16 from 20 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 79813.125
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.

Step 10:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 79813.125
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.

Going ahead to step 11:
0 divided by 8 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 79813.125
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 79813.125 with a remaining 0.0.
