3939503 ÷ 499 
We want to divide 3939503 by 499.

Advancing to step 1:
3 divided by 499 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 499

Step 2:
The number 499 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 499

Advancing to step 3:
499 can be fit into 393 0 times, resulting in a remainder of 393.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 393 after subtracting 0 from 393.
Grab the next digit (9) from the dividend, add it to 393, then carry on: 3939 / 499

Advancing to step 4:
When dividing 3939 by 499, we get 7 with a remainder of 446.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 3493 from 3939 to get 446.
Bring next digit (5) of the dividend behind the 446 and repeat the process: 4465 / 499

Advancing to step 5:
The number 499 fits into 4465 8 times, leaving a remainder of 473.
The next digit of our result is 8. 
Result so far: 78.0
Subtracting 3992 from 4465 leaves us with 473.
Include the next digit (0) from the dividend after 473, then repeat: 4730 / 499

Step 6:
499 can be fit into 4730 9 times, resulting in a remainder of 239.
The next digit of our result is 9. 
Result so far: 789.0
Subtract 4491 from 4730 to get 239.
Bring next digit (3) of the dividend behind the 239 and repeat the process: 2393 / 499

Going ahead to step 7:
499 goes into 2393 4 times with a remainder of 397.
The next digit of our result is 4. 
Result so far: 7894.0
Deduct 1996 from 2393 and we're left with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Moving on to step 8:
The number 499 fits into 3970 7 times, leaving a remainder of 477.
The number 7 becomes the next digit in our result. 
Result so far: 7894.7
If we take 3493 away from 3970, we end up with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Step 9:
4770 divided by 499 is 9 with a remainder of 279.
The number 9 becomes the next digit in our result. 
Result so far: 7894.79
If we take 4491 away from 4770, we end up with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Step 10:
2790 divided by 499 is 5 with a remainder of 295.
The next digit of our result is 5. 
Result so far: 7894.795
If we subtract 2495 from 2790, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 11:
If we divide 2950 by 499, we get 5 and a remainder of 455.
The number 5 becomes the next digit in our result. 
Result so far: 7894.7955
If we take 2495 away from 2950, we end up with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

After the division, we end up with 7894.7955 and a remainder of 0.00455.
