811556 ÷ 40 
Let's see how many times 40 fits into 811556.

On to step 1:
40 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 40

On to step 2:
40 goes into 81 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 80 from 81, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 40

Moving on to step 3:
The number 40 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 11 leaves us with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 40

On to step 4:
When dividing 115 by 40, we get 2 with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
Subtract 80 from 115 to get 35.
Take the next digit (5) from the dividend and append it to 35, then repeat: 355 / 40

Step 5:
40 goes into 355 8 times with a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 2028.0
The remainder is 35 after subtracting 320 from 355.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 40

Step 6:
When dividing 356 by 40, we get 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 20288.0
Deduct 320 from 356 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
360 divided by 40 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 20288.9
Deduct 360 from 360 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.

On to step 8:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20288.9
Subtract 0 from 0 to 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.

Moving on to step 9:
0 divided by 40 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20288.9
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.

After the division, we end up with 20288.9 and a remainder of 0.0.
