We divide 549858 by 80
We want to divide 549858 by 80.

On to step 1:
When dividing 5 by 80, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 80

Moving on to step 2:
If we divide 54 by 80, we get 0 and a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Include the next digit (9) from the dividend after 54, then repeat: 549 / 80

Let's proceed to step 3:
549 divided by 80 is 6 with a remainder of 69.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 480 from 549 leaves us with 69.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 80

Step 4:
The number 80 fits into 698 8 times, leaving a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 68.0
If we take 640 away from 698, we end up with 58.
Include the next digit (5) from the dividend after 58, then repeat: 585 / 80

Let's proceed to step 5:
If we divide 585 by 80, we get 7 and a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 687.0
Subtract 560 from 585 to get 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 80

Going ahead to step 6:
The number 80 fits into 258 3 times, leaving a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 6873.0
Deduct 240 from 258 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
180 divided by 80 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 6873.2
The remainder is 20 after subtracting 160 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
The number 80 fits into 200 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 6873.22
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.

In conclusion, the division gives 6873.22 with a balance of 0.04.
