20039 ÷ 49 
Our goal is to divide 20039 by 49.

Step 1:
2 divided by 49 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 49

Let's proceed to step 2:
20 divided by 49 is 0 with a remainder of 20.
The next digit of our result is 0. 
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 / 49

Let's proceed to step 3:
When dividing 200 by 49, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 196 from 200, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 49

Advancing to step 4:
49 goes into 43 0 times with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 49

Going ahead to step 5:
The number 49 fits into 439 8 times, leaving a remainder of 47.
The next digit of our result is 8. 
Result so far: 408.0
If we take 392 away from 439, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 6:
The number 49 fits into 470 9 times, leaving a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 408.9
The remainder is 29 after subtracting 441 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
When dividing 290 by 49, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 408.95
Subtracting 245 from 290 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
49 can be fit into 450 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 408.959
The remainder is 9 after subtracting 441 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
49 goes into 90 1 times with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 408.9591
If we subtract 49 from 90, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 10:
The number 49 fits into 410 8 times, leaving a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 408.95918
Deduct 392 from 410 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
49 goes into 180 3 times with a remainder of 33.
The next digit of our result is 3. 
Result so far: 408.959183
If we subtract 147 from 180, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 12:
49 goes into 330 6 times with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 408.9591836
The remainder is 36 after subtracting 294 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
49 can be fit into 360 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 408.95918367
If we subtract 343 from 360, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 408.95918367 with a remaining 1.7e-08.
