3994310 ÷ 493 
Our goal is to divide 3994310 by 493.

Advancing to step 1:
If we divide 3 by 493, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 493

Step 2:
The number 493 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 493

Let's proceed to step 3:
The number 493 fits into 399 0 times, leaving a remainder of 399.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 399 to get 399.
Take the next digit (4) from the dividend and append it to 399, then repeat: 3994 / 493

Step 4:
The number 493 fits into 3994 8 times, leaving a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 3944 from 3994, we get 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 493

Advancing to step 5:
493 can be fit into 503 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 81.0
The remainder is 10 after subtracting 493 from 503.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 493

Going ahead to step 6:
When dividing 101 by 493, we get 0 with a remainder of 101.
Write down 0 as next digit of the result. 
Result so far: 810.0
Subtract 0 from 101 to get 101.
Include the next digit (0) from the dividend after 101, then repeat: 1010 / 493

Advancing to step 7:
If we divide 1010 by 493, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 8102.0
If we subtract 986 from 1010, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
The number 493 fits into 240 0 times, leaving a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 8102.0
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 9:
When dividing 2400 by 493, we get 4 with a remainder of 428.
The next digit of our result is 4. 
Result so far: 8102.04
If we take 1972 away from 2400, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 10:
4280 divided by 493 is 8 with a remainder of 336.
The next digit of our result is 8. 
Result so far: 8102.048
If we subtract 3944 from 4280, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 11:
3360 divided by 493 is 6 with a remainder of 402.
Put 6 as the next digit of the answer. 
Result so far: 8102.0486
If we subtract 2958 from 3360, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 12:
When dividing 4020 by 493, we get 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 8102.04868
Subtracting 3944 from 4020 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 13:
The number 493 fits into 760 1 times, leaving a remainder of 267.
The number 1 becomes the next digit in our result. 
Result so far: 8102.048681
The remainder is 267 after subtracting 493 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Step 14:
If we divide 2670 by 493, we get 5 and a remainder of 205.
Write down 5 as next digit of the result. 
Result so far: 8102.0486815
Deduct 2465 from 2670 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 15:
If we divide 2050 by 493, we get 4 and a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 8102.04868154
If we subtract 1972 from 2050, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

After the division, we end up with 8102.04868154 and a remainder of 7.8e-08.
