We divide 493391 by 40
We want to divide 493391 by 40.

Moving on to step 1:
40 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 40

Step 2:
When dividing 49 by 40, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 40 from 49 and we're left with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 40

Moving on to step 3:
The number 40 fits into 93 2 times, leaving a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 80 away from 93, we end up with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 40

Advancing to step 4:
If we divide 133 by 40, we get 3 and a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Subtracting 120 from 133 leaves us with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 40

Going ahead to step 5:
When dividing 139 by 40, we get 3 with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 1233.0
Subtract 120 from 139 to get 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 40

Let's proceed to step 6:
If we divide 191 by 40, we get 4 and a remainder of 31.
The next digit of our result is 4. 
Result so far: 12334.0
Subtracting 160 from 191 leaves us 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.

Moving on to step 7:
40 goes into 310 7 times with a remainder of 30.
The next digit of our result is 7. 
Result so far: 12334.7
The remainder is 30 after subtracting 280 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
300 divided by 40 is 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 12334.77
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 12334.77, and the remainder is 0.02.
