We're dividing 639461 by 8 
We want to figure out the number of times 639461 can be divided by 8.

Going ahead to step 1:
8 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 8

Going ahead to step 2:
63 divided by 8 is 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 7 after subtracting 56 from 63.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 8

On to step 3:
If we divide 79 by 8, we get 9 and a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 79.0
If we subtract 72 from 79, we get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 8

Step 4:
8 goes into 74 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 799.0
Deduct 72 from 74 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 8

Going ahead to step 5:
26 divided by 8 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 7993.0
If we take 24 away from 26, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 8

Going ahead to step 6:
The number 8 fits into 21 2 times, leaving a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 79932.0
Subtract 16 from 21 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
The number 8 fits into 50 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 79932.6
Deduct 48 from 50 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.

Moving on to step 8:
8 goes into 20 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 79932.62
Deduct 16 from 20 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.

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: 79932.625
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.

Step 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 79932.625
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.

Moving on to step 11:
0 divided by 8 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 79932.625
Deduct 0 from 0 and we're left 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 79932.625 with a balance of 0.0.
