We're dividing 809346 by 80 
Let's see how many times 80 fits into 809346.

On to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 80

Going ahead to step 2:
80 can be fit into 80 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 80 from 80 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 80

Advancing to step 3:
If we divide 9 by 80, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 80

Going ahead to step 4:
The number 80 fits into 93 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 101.0
The remainder is 13 after subtracting 80 from 93.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 80

Going ahead to step 5:
134 divided by 80 is 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 1011.0
Subtract 80 from 134 to get 54.
Append the next digit (6) from the dividend to 54 and continue with: 546 / 80

Step 6:
If we divide 546 by 80, we get 6 and a remainder of 66.
The next digit of our result is 6. 
Result so far: 10116.0
Subtract 480 from 546 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 7:
When dividing 660 by 80, we get 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 10116.8
Subtract 640 from 660 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 8:
If we divide 200 by 80, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 10116.82
Subtracting 160 from 200 leaves us 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.

Moving on to step 9:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10116.825
Subtract 400 from 400 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 10116.825
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10116.825
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 final result is 10116.825 with a remainder of 0.0.
