We're dividing 39668919 by 493 
We want to figure out the number of times 39668919 can be divided by 493.

Step 1:
3 divided by 493 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 493

Advancing to step 2:
493 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 493

On to step 3:
396 divided by 493 is 0 with a remainder of 396.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 396 and we're left with 396.
Bring next digit (6) of the dividend behind the 396 and repeat the process: 3966 / 493

Let's proceed to step 4:
If we divide 3966 by 493, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 3944 from 3966 leaves us with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 493

Step 5:
493 can be fit into 228 0 times, resulting in a remainder of 228.
The next digit of our result is 0. 
Result so far: 80.0
Deduct 0 from 228 and we're left with 228.
Take the next digit (9) from the dividend and append it to 228, then repeat: 2289 / 493

Advancing to step 6:
2289 divided by 493 is 4 with a remainder of 317.
Put 4 as the next digit of the answer. 
Result so far: 804.0
Subtract 1972 from 2289 to get 317.
Grab the next digit (1) from the dividend, add it to 317, then carry on: 3171 / 493

Step 7:
When dividing 3171 by 493, we get 6 with a remainder of 213.
Put 6 as the next digit of the answer. 
Result so far: 8046.0
Deduct 2958 from 3171 and we're left with 213.
Include the next digit (9) from the dividend after 213, then repeat: 2139 / 493

Moving on to step 8:
2139 divided by 493 is 4 with a remainder of 167.
The number 4 becomes the next digit in our result. 
Result so far: 80464.0
If we take 1972 away from 2139, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Step 9:
493 goes into 1670 3 times with a remainder of 191.
Put 3 as the next digit of the answer. 
Result so far: 80464.3
If we subtract 1479 from 1670, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 10:
1910 divided by 493 is 3 with a remainder of 431.
The number 3 becomes the next digit in our result. 
Result so far: 80464.33
If we subtract 1479 from 1910, we get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Our division results in 80464.33 with a remaining 0.431.
