Let's divide 138849 by 50
We're looking to find how many times 50 goes into 138849.

Advancing to step 1:
50 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 50

Moving on to step 2:
The number 50 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 50

Going ahead to step 3:
50 can be fit into 138 2 times, resulting in a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 100 from 138, we get 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 50

Going ahead to step 4:
388 divided by 50 is 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtract 350 from 388 to get 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 50

On to step 5:
50 goes into 384 7 times with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 277.0
The remainder is 34 after subtracting 350 from 384.
Grab the next digit (9) from the dividend, add it to 34, then carry on: 349 / 50

Moving on to step 6:
349 divided by 50 is 6 with a remainder of 49.
The next digit of our result is 6. 
Result so far: 2776.0
Subtracting 300 from 349 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
50 goes into 490 9 times with a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 2776.9
Deduct 450 from 490 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
400 divided by 50 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 2776.98
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2776.98
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
If we divide 0 by 50, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2776.98
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 2776.98 and a remainder of 0.0.
