We divide 849609 by 80
Our goal is to divide 849609 by 80.

Going ahead to step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 80

Let's proceed to step 2:
When dividing 84 by 80, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 80 from 84 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 80

Step 3:
80 goes into 49 0 times with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 49, we get 49.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 80

Let's proceed to step 4:
496 divided by 80 is 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
Deduct 480 from 496 and we're left with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 80

Step 5:
160 divided by 80 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 1062.0
Subtract 160 from 160 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 80

Step 6:
80 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 10620.0
Deduct 0 from 9 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
When dividing 90 by 80, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 10620.1
Subtract 80 from 90 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.

On to step 8:
When dividing 100 by 80, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 10620.11
Subtracting 80 from 100 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 10620.11 with a remaining 0.02.
