638239 divided by 9 
Our goal is to divide 638239 by 9.

Step 1:
The number 9 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 9

On to step 2:
9 goes into 63 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 63 away from 63, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 9

Moving on to step 3:
The number 9 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 9

Going ahead to step 4:
82 divided by 9 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 709.0
Subtract 81 from 82 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 9

Moving on to step 5:
The number 9 fits into 13 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 7091.0
The remainder is 4 after subtracting 9 from 13.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 9

Advancing to step 6:
When dividing 49 by 9, we get 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 70915.0
Subtract 45 from 49 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.

Going ahead to step 7:
When dividing 40 by 9, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 70915.4
Subtract 36 from 40 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 8:
9 can be fit into 40 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 70915.44
Subtract 36 from 40 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.

Our division results in 70915.44 with a remaining 0.004.
