We're dividing 639386 by 9 
Our goal is to divide 639386 by 9.

Moving on to step 1:
When dividing 6 by 9, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 9

Step 2:
9 can be fit into 63 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 0 after subtracting 63 from 63.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 9

Step 3:
9 goes into 9 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Deduct 9 from 9 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 9

Let's proceed to step 4:
If we divide 3 by 9, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 710.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 9

On to step 5:
9 can be fit into 38 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 7104.0
Subtracting 36 from 38 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 9

Moving on to step 6:
If we divide 26 by 9, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 71042.0
Subtract 18 from 26 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
When dividing 80 by 9, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 71042.8
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
80 divided by 9 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 71042.88
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 71042.88, and the remainder is 0.008.
