We're dividing 775999 by 40 
Let's see how many times 40 fits into 775999.

Advancing to step 1:
7 divided by 40 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 40

On to step 2:
77 divided by 40 is 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 37 after subtracting 40 from 77.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 40

Let's proceed to step 3:
40 goes into 375 9 times with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 360 from 375 leaves us with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 40

Going ahead to step 4:
40 goes into 159 3 times with a remainder of 39.
The next digit of our result is 3. 
Result so far: 193.0
Subtract 120 from 159 to get 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 40

Moving on to step 5:
The number 40 fits into 399 9 times, leaving a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 1939.0
Deduct 360 from 399 and we're left with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 40

Going ahead to step 6:
40 can be fit into 399 9 times, resulting in a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 19399.0
Subtracting 360 from 399 leaves us 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:
390 divided by 40 is 9 with a remainder of 30.
The next digit of our result is 9. 
Result so far: 19399.9
Deduct 360 from 390 and we're left 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:
40 can be fit into 300 7 times, resulting in a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 19399.97
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
40 goes into 200 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 19399.975
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 40 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19399.975
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.

Step 11:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 19399.975
If we subtract 0 from 0, we get 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 result is 19399.975 with a remainder of 0.0.
