639202 divided by 8 
We're looking to find how many times 8 goes into 639202.

Advancing to step 1:
8 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 8

Step 2:
8 goes into 63 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 56 from 63 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 8

On to step 3:
79 divided by 8 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 79.0
Subtracting 72 from 79 leaves us with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 8

Step 4:
The number 8 fits into 72 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 799.0
Subtracting 72 from 72 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 8

Step 5:
When dividing 0 by 8, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7990.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 8

Let's proceed to step 6:
8 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 79900.0
Deduct 0 from 2 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 8, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 79900.2
If we subtract 16 from 20, we 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 8:
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: 79900.25
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.

On to step 9:
If we divide 0 by 8, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 79900.25
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.

Advancing to step 10:
8 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 79900.25
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.

After the division, we end up with 79900.25 and a remainder of 0.0.
