755814 ÷ 40 
Let's see how many times 40 fits into 755814.

Step 1:
The number 40 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 40

On to step 2:
If we divide 75 by 40, we get 1 and a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 40 from 75 to get 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 40

Advancing to step 3:
The number 40 fits into 355 8 times, leaving a remainder of 35.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 320 from 355 and we're left with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 40

On to step 4:
The number 40 fits into 358 8 times, leaving a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 188.0
If we take 320 away from 358, we end up with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 40

Step 5:
40 can be fit into 381 9 times, resulting in a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 1889.0
Subtract 360 from 381 to get 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 40

Going ahead to step 6:
40 can be fit into 214 5 times, resulting in a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 18895.0
The remainder is 14 after subtracting 200 from 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
40 can be fit into 140 3 times, resulting in a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 18895.3
If we subtract 120 from 140, 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.

Moving on to step 8:
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: 18895.35
If we take 200 away from 200, 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.

Moving on to step 9:
When dividing 0 by 40, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18895.35
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.

Advancing to step 10:
0 divided by 40 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18895.35
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.

The final result is 18895.35 with a remainder of 0.0.
