We look at the division of 581680 by 99 
We want to figure out the number of times 581680 can be divided by 99.

Advancing to step 1:
When dividing 5 by 99, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 99

Advancing to step 2:
If we divide 58 by 99, we get 0 and a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Grab the next digit (1) from the dividend, add it to 58, then carry on: 581 / 99

Advancing to step 3:
The number 99 fits into 581 5 times, leaving a remainder of 86.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 495 away from 581, we end up with 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 99

Advancing to step 4:
The number 99 fits into 866 8 times, leaving a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Deduct 792 from 866 and we're left with 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 99

Advancing to step 5:
The number 99 fits into 748 7 times, leaving a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 587.0
Subtracting 693 from 748 leaves us with 55.
Fetch the next digit (0) from the dividend, attach it to 55 and continue: 550 / 99

Step 6:
When dividing 550 by 99, we get 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 5875.0
Subtracting 495 from 550 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 7:
99 goes into 550 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 5875.5
Deduct 495 from 550 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 8:
99 goes into 550 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 5875.55
If we take 495 away from 550, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 5875.55 and a remainder of 0.055.
