825809 divided by 80 
We want to divide 825809 by 80.

Step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 80

Step 2:
If we divide 82 by 80, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 80 from 82 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 80

Let's proceed to step 3:
25 divided by 80 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 25 to get 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 80

Advancing to step 4:
80 can be fit into 258 3 times, resulting in a remainder of 18.
The next digit of our result is 3. 
Result so far: 103.0
The remainder is 18 after subtracting 240 from 258.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 80

Going ahead to step 5:
If we divide 180 by 80, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 1032.0
Subtracting 160 from 180 leaves us with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 80

Advancing to step 6:
80 can be fit into 209 2 times, resulting in a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 10322.0
Deduct 160 from 209 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
The number 80 fits into 490 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 10322.6
Subtract 480 from 490 to get 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.
The next digit of our result is 1. 
Result so far: 10322.61
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.

On to step 9:
80 goes into 200 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 10322.612
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.

On to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10322.6125
Subtracting 400 from 400 leaves us 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.

Advancing to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10322.6125
Subtract 0 from 0 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.

Let's proceed to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10322.6125
Subtracting 0 from 0 leaves us 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.

Our division results in 10322.6125 with a remaining 0.0.
