806243 divided by 40 
We want to divide 806243 by 40.

On to step 1:
If we divide 8 by 40, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 40

On to step 2:
80 divided by 40 is 2 with 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 (6) from the dividend, add it to 0, then carry on: 6 / 40

Let's proceed to step 3:
40 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 40

Advancing to step 4:
The number 40 fits into 62 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 201.0
If we subtract 40 from 62, we get 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 40

Step 5:
40 can be fit into 224 5 times, resulting in a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 2015.0
Subtract 200 from 224 to get 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 40

Going ahead to step 6:
The number 40 fits into 243 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 20156.0
If we take 240 away from 243, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
40 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 20156.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
40 can be fit into 300 7 times, resulting in a remainder of 20.
The next digit of our result is 7. 
Result so far: 20156.07
If we subtract 280 from 300, 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.

On to step 9:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 20156.075
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.

Step 10:
40 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20156.075
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.

Going ahead to step 11:
If we divide 0 by 40, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20156.075
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 quotient of the division is 20156.075, and the remainder is 0.0.
