780279 divided by 40 
We're looking to find how many times 40 goes into 780279.

Step 1:
If we divide 7 by 40, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 40

Moving on to step 2:
78 divided by 40 is 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 38 after subtracting 40 from 78.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 40

Moving on to step 3:
380 divided by 40 is 9 with a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 360 from 380 leaves us with 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 40

Step 4:
40 can be fit into 202 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 195.0
Deduct 200 from 202 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 40

Going ahead to step 5:
If we divide 27 by 40, we get 0 and a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 1950.0
If we subtract 0 from 27, we get 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 40

Going ahead to step 6:
40 can be fit into 279 6 times, resulting in a remainder of 39.
Put 6 as the next digit of the answer. 
Result so far: 19506.0
If we take 240 away from 279, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
The number 40 fits into 390 9 times, leaving a remainder of 30.
The next digit of our result is 9. 
Result so far: 19506.9
If we take 360 away from 390, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 40 is 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 19506.97
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 40 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 19506.975
Deduct 200 from 200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 19506.975
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19506.975
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 19506.975, with a leftover of 0.0.
