We're dividing 139439 by 49 
We want to divide 139439 by 49.

Going ahead to step 1:
49 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 49

Going ahead to step 2:
When dividing 13 by 49, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 49

Step 3:
49 goes into 139 2 times with a remainder of 41.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 98 from 139, we get 41.
Append the next digit (4) from the dividend to 41 and continue with: 414 / 49

Advancing to step 4:
49 goes into 414 8 times with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 392 from 414 to get 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 49

On to step 5:
The number 49 fits into 223 4 times, leaving a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 284.0
If we subtract 196 from 223, we get 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 49

Advancing to step 6:
49 can be fit into 279 5 times, resulting in a remainder of 34.
The next digit of our result is 5. 
Result so far: 2845.0
If we take 245 away from 279, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
If we divide 340 by 49, we get 6 and a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 2845.6
Subtract 294 from 340 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
460 divided by 49 is 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 2845.69
The remainder is 19 after subtracting 441 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
49 can be fit into 190 3 times, resulting in a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 2845.693
If we subtract 147 from 190, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 10:
When dividing 430 by 49, we get 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 2845.6938
Deduct 392 from 430 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
If we divide 380 by 49, we get 7 and a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 2845.69387
Deduct 343 from 380 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 12:
370 divided by 49 is 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 2845.693877
If we take 343 away from 370, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 2845.693877 with a remainder of 2.7e-06.
