We divide 809181 by 40
Our goal is to divide 809181 by 40.

Going ahead to step 1:
40 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 40

Step 2:
If we divide 80 by 40, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 80 from 80, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 40

On to step 3:
40 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 40

Step 4:
If we divide 91 by 40, we get 2 and a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 202.0
Subtract 80 from 91 to get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 40

Step 5:
When dividing 118 by 40, we get 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 2022.0
The remainder is 38 after subtracting 80 from 118.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 40

Going ahead to step 6:
If we divide 381 by 40, we get 9 and a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 20229.0
If we take 360 away from 381, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
40 goes into 210 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 20229.5
Deduct 200 from 210 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.

Advancing to step 8:
If we divide 100 by 40, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 20229.52
If we take 80 away from 100, 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.

On to step 9:
The number 40 fits into 200 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 20229.525
Subtract 200 from 200 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.

Let's proceed to step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20229.525
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.

Advancing to step 11:
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: 20229.525
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.

The quotient of the division is 20229.525, and the remainder is 0.0.
