We look at the division of 49120702 by 39 
We want to divide 49120702 by 39.

On to step 1:
The number 39 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 39

Step 2:
If we divide 49 by 39, we get 1 and a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 39 from 49, we get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 39

Going ahead to step 3:
39 can be fit into 101 2 times, resulting in a remainder of 23.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 78 from 101 and we're left with 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 39

Advancing to step 4:
232 divided by 39 is 5 with a remainder of 37.
The next digit of our result is 5. 
Result so far: 125.0
The remainder is 37 after subtracting 195 from 232.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 39

Going ahead to step 5:
39 goes into 370 9 times with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 1259.0
Subtracting 351 from 370 leaves us with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 39

Step 6:
The number 39 fits into 197 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 12595.0
If we take 195 away from 197, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 39

Step 7:
20 divided by 39 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 125950.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 39

Step 8:
39 can be fit into 202 5 times, resulting in a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 1259505.0
Subtract 195 from 202 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.

Advancing to step 9:
The number 39 fits into 70 1 times, leaving a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1259505.1
The remainder is 31 after subtracting 39 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
39 goes into 310 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 1259505.17
Deduct 273 from 310 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.

Step 11:
If we divide 370 by 39, we get 9 and a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 1259505.179
Subtract 351 from 370 to 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 12:
The number 39 fits into 190 4 times, leaving a remainder of 34.
The next digit of our result is 4. 
Result so far: 1259505.1794
Deduct 156 from 190 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.

Going ahead to step 13:
The number 39 fits into 340 8 times, leaving a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 1259505.17948
If we take 312 away from 340, we end up 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.

Going ahead to step 14:
39 can be fit into 280 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 1259505.179487
Subtract 273 from 280 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 15:
If we divide 70 by 39, we get 1 and a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1259505.1794871
Deduct 39 from 70 and we're left 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.

Advancing to step 16:
When dividing 310 by 39, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 1259505.17948717
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final outcome is 1259505.17948717, with a leftover of 3.7e-08.
