Let's divide 832409 by 40
We're looking to find how many times 40 goes into 832409.

Moving on to step 1:
If we divide 8 by 40, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 40

Going ahead to step 2:
If we divide 83 by 40, we get 2 and a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 80 from 83 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 40

Going ahead to step 3:
32 divided by 40 is 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 32 leaves us with 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 40

Step 4:
When dividing 324 by 40, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 208.0
Subtracting 320 from 324 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 40

Advancing to step 5:
40 can be fit into 40 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 2081.0
If we subtract 40 from 40, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 40

Step 6:
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: 20810.0
If we take 0 away from 9, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
If we divide 90 by 40, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 20810.2
If we take 80 away from 90, we end up 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.

Let's proceed to step 8:
If we divide 100 by 40, we get 2 and a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 20810.22
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.

After the division, we end up with 20810.22 and a remainder of 0.02.
