3999992 ÷ 494 
We want to figure out the number of times 3999992 can be divided by 494.

Moving on to step 1:
494 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 494

Let's proceed to step 2:
494 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 494

Advancing to step 3:
If we divide 399 by 494, we get 0 and a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 399 leaves us with 399.
Include the next digit (9) from the dividend after 399, then repeat: 3999 / 494

Step 4:
494 goes into 3999 8 times with a remainder of 47.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 3952 from 3999, we get 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 494

On to step 5:
494 can be fit into 479 0 times, resulting in a remainder of 479.
Write down 0 as next digit of the result. 
Result so far: 80.0
Deduct 0 from 479 and we're left with 479.
Append the next digit (9) from the dividend to 479 and continue with: 4799 / 494

Advancing to step 6:
494 can be fit into 4799 9 times, resulting in a remainder of 353.
Record the quotient 9 as the next digit in the result. 
Result so far: 809.0
If we take 4446 away from 4799, we end up with 353.
Take the next digit (2) from the dividend and append it to 353, then repeat: 3532 / 494

Advancing to step 7:
The number 494 fits into 3532 7 times, leaving a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 8097.0
Deduct 3458 from 3532 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 8:
494 can be fit into 740 1 times, resulting in a remainder of 246.
The number 1 becomes the next digit in our result. 
Result so far: 8097.1
Subtract 494 from 740 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 9:
2460 divided by 494 is 4 with a remainder of 484.
The next digit of our result is 4. 
Result so far: 8097.14
If we subtract 1976 from 2460, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 10:
494 can be fit into 4840 9 times, resulting in a remainder of 394.
Record the quotient 9 as the next digit in the result. 
Result so far: 8097.149
Subtracting 4446 from 4840 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 11:
494 can be fit into 3940 7 times, resulting in a remainder of 482.
Put 7 as the next digit of the answer. 
Result so far: 8097.1497
Subtract 3458 from 3940 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 12:
494 goes into 4820 9 times with a remainder of 374.
Record the quotient 9 as the next digit in the result. 
Result so far: 8097.14979
Subtract 4446 from 4820 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 13:
494 goes into 3740 7 times with a remainder of 282.
Write down 7 as next digit of the result. 
Result so far: 8097.149797
Subtract 3458 from 3740 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 14:
2820 divided by 494 is 5 with a remainder of 350.
Record the quotient 5 as the next digit in the result. 
Result so far: 8097.1497975
Deduct 2470 from 2820 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 15:
494 can be fit into 3500 7 times, resulting in a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 8097.14979757
Subtract 3458 from 3500 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 8097.14979757 with a remainder of 4.2e-08.
