841812 ÷ 409 
Our goal is to divide 841812 by 409.

On to step 1:
409 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 409

Let's proceed to step 2:
84 divided by 409 is 0 with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Fetch the next digit (1) from the dividend, attach it to 84 and continue: 841 / 409

Advancing to step 3:
409 can be fit into 841 2 times, resulting in a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 818 away from 841, we end up with 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 409

Moving on to step 4:
409 goes into 238 0 times with a remainder of 238.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 238, we get 238.
Fetch the next digit (1) from the dividend, attach it to 238 and continue: 2381 / 409

Moving on to step 5:
409 can be fit into 2381 5 times, resulting in a remainder of 336.
The number 5 becomes the next digit in our result. 
Result so far: 205.0
If we take 2045 away from 2381, we end up with 336.
Take the next digit (2) from the dividend and append it to 336, then repeat: 3362 / 409

Moving on to step 6:
3362 divided by 409 is 8 with a remainder of 90.
Write down 8 as next digit of the result. 
Result so far: 2058.0
If we take 3272 away from 3362, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 7:
409 goes into 900 2 times with a remainder of 82.
Record the quotient 2 as the next digit in the result. 
Result so far: 2058.2
The remainder is 82 after subtracting 818 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 8:
820 divided by 409 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2058.22
The remainder is 2 after subtracting 818 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 2058.22 with a remainder of 0.002.
