We look at the division of 406817 by 80 
We want to divide 406817 by 80.

Going ahead to step 1:
80 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 80

Moving on to step 2:
80 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 80

Step 3:
The number 80 fits into 406 5 times, leaving a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 400 from 406, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 80

Let's proceed to step 4:
80 can be fit into 68 0 times, resulting in a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we subtract 0 from 68, we get 68.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 80

Let's proceed to step 5:
If we divide 681 by 80, we get 8 and a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 508.0
Deduct 640 from 681 and we're left with 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 80

Advancing to step 6:
80 goes into 417 5 times with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 5085.0
If we take 400 away from 417, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
80 can be fit into 170 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 5085.2
Deduct 160 from 170 and we're left 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:
80 goes into 100 1 times with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 5085.21
Subtract 80 from 100 to 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.

Let's proceed to step 9:
200 divided by 80 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 5085.212
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5085.2125
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.

Let's proceed to step 11:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5085.2125
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.

On to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5085.2125
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.

The quotient of the division is 5085.2125, and the remainder is 0.0.
