80494676 ÷ 409 
Our goal is to divide 80494676 by 409.

Let's proceed to step 1:
8 divided by 409 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 409

Moving on to step 2:
409 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Grab the next digit (4) from the dividend, add it to 80, then carry on: 804 / 409

Let's proceed to step 3:
409 can be fit into 804 1 times, resulting in a remainder of 395.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 409 from 804 leaves us with 395.
Bring next digit (9) of the dividend behind the 395 and repeat the process: 3959 / 409

Going ahead to step 4:
When dividing 3959 by 409, we get 9 with a remainder of 278.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 3681 from 3959 to get 278.
Take the next digit (4) from the dividend and append it to 278, then repeat: 2784 / 409

Step 5:
The number 409 fits into 2784 6 times, leaving a remainder of 330.
The number 6 becomes the next digit in our result. 
Result so far: 196.0
Deduct 2454 from 2784 and we're left with 330.
Include the next digit (6) from the dividend after 330, then repeat: 3306 / 409

Advancing to step 6:
3306 divided by 409 is 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 1968.0
Subtracting 3272 from 3306 leaves us with 34.
Include the next digit (7) from the dividend after 34, then repeat: 347 / 409

Moving on to step 7:
When dividing 347 by 409, we get 0 with a remainder of 347.
Record the quotient 0 as the next digit in the result. 
Result so far: 19680.0
If we take 0 away from 347, we end up with 347.
Append the next digit (6) from the dividend to 347 and continue with: 3476 / 409

Step 8:
3476 divided by 409 is 8 with a remainder of 204.
The number 8 becomes the next digit in our result. 
Result so far: 196808.0
The remainder is 204 after subtracting 3272 from 3476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 9:
When dividing 2040 by 409, we get 4 with a remainder of 404.
Write down 4 as next digit of the result. 
Result so far: 196808.4
Subtract 1636 from 2040 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 10:
The number 409 fits into 4040 9 times, leaving a remainder of 359.
The next digit of our result is 9. 
Result so far: 196808.49
If we subtract 3681 from 4040, we get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

On to step 11:
The number 409 fits into 3590 8 times, leaving a remainder of 318.
Write down 8 as next digit of the result. 
Result so far: 196808.498
Subtract 3272 from 3590 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 12:
The number 409 fits into 3180 7 times, leaving a remainder of 317.
Write down 7 as next digit of the result. 
Result so far: 196808.4987
The remainder is 317 after subtracting 2863 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Going ahead to step 13:
If we divide 3170 by 409, we get 7 and a remainder of 307.
Write down 7 as next digit of the result. 
Result so far: 196808.49877
If we subtract 2863 from 3170, we get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

The quotient of the division is 196808.49877, and the remainder is 0.000307.
