139144 ÷ 49 
We're looking to find how many times 49 goes into 139144.

Moving on to step 1:
49 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 49

Going ahead to step 2:
13 divided by 49 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 49

On to step 3:
49 can be fit into 139 2 times, resulting in a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 98 from 139, we get 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 49

Advancing to step 4:
When dividing 411 by 49, we get 8 with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 392 from 411, we get 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 49

Let's proceed to step 5:
The number 49 fits into 194 3 times, leaving a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 283.0
Subtract 147 from 194 to get 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 49

Step 6:
When dividing 474 by 49, we get 9 with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 2839.0
If we take 441 away from 474, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
49 goes into 330 6 times with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 2839.6
Subtracting 294 from 330 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
When dividing 360 by 49, we get 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 2839.67
If we take 343 away from 360, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
The number 49 fits into 170 3 times, leaving a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 2839.673
If we subtract 147 from 170, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 10:
49 can be fit into 230 4 times, resulting in a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 2839.6734
Deduct 196 from 230 and we're left 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.

Advancing to step 11:
340 divided by 49 is 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 2839.67346
The remainder is 46 after subtracting 294 from 340.
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 12:
460 divided by 49 is 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 2839.673469
If we subtract 441 from 460, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
49 can be fit into 190 3 times, resulting in a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 2839.6734693
Subtracting 147 from 190 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 14:
430 divided by 49 is 8 with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 2839.67346938
If we subtract 392 from 430, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 2839.67346938 with a remaining 3.8e-08.
