80644 ÷ 99 
We want to divide 80644 by 99.

Moving on to step 1:
If we divide 8 by 99, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 99

On to step 2:
80 divided by 99 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 99

Moving on to step 3:
If we divide 806 by 99, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 792 from 806 to get 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 99

Step 4:
When dividing 144 by 99, we get 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
The remainder is 45 after subtracting 99 from 144.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 99

Moving on to step 5:
The number 99 fits into 454 4 times, leaving a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 814.0
The remainder is 58 after subtracting 396 from 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 6:
If we divide 580 by 99, we get 5 and a remainder of 85.
The next digit of our result is 5. 
Result so far: 814.5
Subtract 495 from 580 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 7:
99 goes into 850 8 times with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 814.58
If we take 792 away from 850, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 8:
If we divide 580 by 99, we get 5 and a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 814.585
If we subtract 495 from 580, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 9:
If we divide 850 by 99, we get 8 and a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 814.5858
If we take 792 away from 850, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
99 goes into 580 5 times with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 814.58585
If we take 495 away from 580, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 11:
The number 99 fits into 850 8 times, leaving a remainder of 58.
The next digit of our result is 8. 
Result so far: 814.585858
The remainder is 58 after subtracting 792 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 12:
The number 99 fits into 580 5 times, leaving a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 814.5858585
Subtract 495 from 580 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 13:
When dividing 850 by 99, we get 8 with a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 814.58585858
Deduct 792 from 850 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 814.58585858 with a remaining 5.8e-08.
