We divide 558648 by 81
Our goal is to divide 558648 by 81.

Step 1:
When dividing 5 by 81, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 81

Going ahead to step 2:
If we divide 55 by 81, we get 0 and a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Grab the next digit (8) from the dividend, add it to 55, then carry on: 558 / 81

On to step 3:
When dividing 558 by 81, we get 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 72 after subtracting 486 from 558.
Bring next digit (6) of the dividend behind the 72 and repeat the process: 726 / 81

Step 4:
726 divided by 81 is 8 with a remainder of 78.
The next digit of our result is 8. 
Result so far: 68.0
If we take 648 away from 726, we end up with 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 81

Going ahead to step 5:
81 goes into 784 9 times with a remainder of 55.
The next digit of our result is 9. 
Result so far: 689.0
Subtracting 729 from 784 leaves us with 55.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 81

Let's proceed to step 6:
If we divide 558 by 81, we get 6 and a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 6896.0
Subtract 486 from 558 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 7:
81 can be fit into 720 8 times, resulting in a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 6896.8
If we subtract 648 from 720, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 8:
81 can be fit into 720 8 times, resulting in a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 6896.88
The remainder is 72 after subtracting 648 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 6896.88 with a remaining 0.072.
