759509 ÷ 40 
Let's see how many times 40 fits into 759509.

Going ahead to step 1:
40 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 40

On to step 2:
The number 40 fits into 75 1 times, leaving a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 40 from 75, we get 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 40

Moving on to step 3:
The number 40 fits into 359 8 times, leaving a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 320 from 359 leaves us with 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 40

Moving on to step 4:
The number 40 fits into 395 9 times, leaving a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 189.0
If we subtract 360 from 395, we get 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 40

Let's proceed to step 5:
40 goes into 350 8 times with a remainder of 30.
The next digit of our result is 8. 
Result so far: 1898.0
If we subtract 320 from 350, we get 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 40

Step 6:
40 goes into 309 7 times with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 18987.0
If we subtract 280 from 309, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
If we divide 290 by 40, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 18987.7
Deduct 280 from 290 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 40, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 18987.72
The remainder is 20 after subtracting 80 from 100.
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.
Record the quotient 5 as the next digit in the result. 
Result so far: 18987.725
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.

Going ahead to step 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18987.725
Deduct 0 from 0 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.

Let's proceed to step 11:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18987.725
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 18987.725, and the remainder is 0.0.
