939840 ÷ 49 
We want to divide 939840 by 49.

Step 1:
9 divided by 49 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 49

Step 2:
The number 49 fits into 93 1 times, leaving a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 49 from 93 and we're left with 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 49

Advancing to step 3:
The number 49 fits into 449 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 19.0
If we take 441 away from 449, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 49

Going ahead to step 4:
When dividing 88 by 49, we get 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 191.0
Deduct 49 from 88 and we're left with 39.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 49

Let's proceed to step 5:
If we divide 394 by 49, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 1918.0
Subtract 392 from 394 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 49

Moving on to step 6:
When dividing 20 by 49, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 19180.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
The number 49 fits into 200 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 19180.4
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
49 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 19180.4
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
When dividing 400 by 49, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 19180.408
If we take 392 away from 400, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
When dividing 80 by 49, we get 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 19180.4081
If we take 49 away from 80, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
If we divide 310 by 49, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 19180.40816
Subtracting 294 from 310 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
49 goes into 160 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 19180.408163
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 13:
The number 49 fits into 130 2 times, leaving a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 19180.4081632
The remainder is 32 after subtracting 98 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
When dividing 320 by 49, we get 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 19180.40816326
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 19180.40816326, with a leftover of 2.6e-08.
