409674 divided by 80 
We want to divide 409674 by 80.

On to step 1:
If we divide 4 by 80, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 80

On to step 2:
The number 80 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (9) of the dividend behind the 40 and repeat the process: 409 / 80

Let's proceed to step 3:
409 divided by 80 is 5 with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 400 from 409 leaves us with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 80

On to step 4:
The number 80 fits into 96 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtract 80 from 96 to get 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 80

Moving on to step 5:
When dividing 167 by 80, we get 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 512.0
Subtracting 160 from 167 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 80

Going ahead to step 6:
74 divided by 80 is 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 5120.0
Subtract 0 from 74 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 7:
80 can be fit into 740 9 times, resulting in a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 5120.9
If we subtract 720 from 740, 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.

Step 8:
80 goes into 200 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 5120.92
If we subtract 160 from 200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5120.925
Deduct 400 from 400 and we're left 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.

Going ahead to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5120.925
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.

Moving on to step 11:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5120.925
Deduct 0 from 0 and we're left 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 5120.925, and the remainder is 0.0.
