We're dividing 13139 by 49 
Let's see how many times 49 fits into 13139.

Going ahead to step 1:
The number 49 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 49

Moving on to step 2:
49 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 49

On to step 3:
The number 49 fits into 131 2 times, leaving a remainder of 33.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 98 from 131 and we're left with 33.
Take the next digit (3) from the dividend and append it to 33, then repeat: 333 / 49

On to step 4:
The number 49 fits into 333 6 times, leaving a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 26.0
The remainder is 39 after subtracting 294 from 333.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 49

On to step 5:
The number 49 fits into 399 8 times, leaving a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 268.0
Subtracting 392 from 399 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 6:
49 goes into 70 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 268.1
The remainder is 21 after subtracting 49 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
210 divided by 49 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 268.14
If we take 196 away from 210, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
49 can be fit into 140 2 times, resulting in a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 268.142
The remainder is 42 after subtracting 98 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
When dividing 420 by 49, we get 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 268.1428
Subtracting 392 from 420 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
If we divide 280 by 49, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 268.14285
Subtracting 245 from 280 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
49 can be fit into 350 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 268.142857
Subtract 343 from 350 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
70 divided by 49 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 268.1428571
Subtracting 49 from 70 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 13:
The number 49 fits into 210 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 268.14285714
Subtracting 196 from 210 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 268.14285714 with a remainder of 1.4e-08.
