Let's divide 20004709 by 639
We're looking to find how many times 639 goes into 20004709.

Moving on to step 1:
When dividing 2 by 639, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 639

Going ahead to step 2:
When dividing 20 by 639, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 639

Advancing to step 3:
When dividing 200 by 639, we get 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 200, we get 200.
Fetch the next digit (0) from the dividend, attach it to 200 and continue: 2000 / 639

Step 4:
639 can be fit into 2000 3 times, resulting in a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 1917 from 2000 to get 83.
Append the next digit (4) from the dividend to 83 and continue with: 834 / 639

Going ahead to step 5:
The number 639 fits into 834 1 times, leaving a remainder of 195.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtracting 639 from 834 leaves us with 195.
Bring next digit (7) of the dividend behind the 195 and repeat the process: 1957 / 639

Going ahead to step 6:
The number 639 fits into 1957 3 times, leaving a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 313.0
Subtracting 1917 from 1957 leaves us with 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 639

Going ahead to step 7:
639 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 3130.0
Subtracting 0 from 400 leaves us with 400.
Include the next digit (9) from the dividend after 400, then repeat: 4009 / 639

Advancing to step 8:
When dividing 4009 by 639, we get 6 with a remainder of 175.
Use 6 as the next digit of our solution. 
Result so far: 31306.0
Subtracting 3834 from 4009 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 9:
639 goes into 1750 2 times with a remainder of 472.
The next digit of our result is 2. 
Result so far: 31306.2
Subtract 1278 from 1750 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 10:
When dividing 4720 by 639, we get 7 with a remainder of 247.
The next digit of our result is 7. 
Result so far: 31306.27
The remainder is 247 after subtracting 4473 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 11:
2470 divided by 639 is 3 with a remainder of 553.
The next digit of our result is 3. 
Result so far: 31306.273
If we subtract 1917 from 2470, we get 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Step 12:
639 goes into 5530 8 times with a remainder of 418.
The next digit of our result is 8. 
Result so far: 31306.2738
If we take 5112 away from 5530, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 13:
639 goes into 4180 6 times with a remainder of 346.
Write down 6 as next digit of the result. 
Result so far: 31306.27386
The remainder is 346 after subtracting 3834 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 14:
3460 divided by 639 is 5 with a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 31306.273865
Subtracting 3195 from 3460 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 15:
When dividing 2650 by 639, we get 4 with a remainder of 94.
The next digit of our result is 4. 
Result so far: 31306.2738654
Subtracting 2556 from 2650 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 16:
When dividing 940 by 639, we get 1 with a remainder of 301.
Write down 1 as next digit of the result. 
Result so far: 31306.27386541
If we subtract 639 from 940, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

The final outcome is 31306.27386541, with a leftover of 3.01e-07.
