80423 divided by 81 
We want to divide 80423 by 81.

Moving on to step 1:
81 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 81

Going ahead to step 2:
The number 81 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 81

On to step 3:
When dividing 804 by 81, we get 9 with a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 729 from 804 leaves us with 75.
Take the next digit (2) from the dividend and append it to 75, then repeat: 752 / 81

On to step 4:
When dividing 752 by 81, we get 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtracting 729 from 752 leaves us with 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 81

On to step 5:
When dividing 233 by 81, we get 2 with a remainder of 71.
Write down 2 as next digit of the result. 
Result so far: 992.0
The remainder is 71 after subtracting 162 from 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 6:
710 divided by 81 is 8 with a remainder of 62.
The next digit of our result is 8. 
Result so far: 992.8
If we take 648 away from 710, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 7:
The number 81 fits into 620 7 times, leaving a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 992.87
Subtracting 567 from 620 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 8:
530 divided by 81 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 992.876
If we subtract 486 from 530, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
The number 81 fits into 440 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 992.8765
Subtracting 405 from 440 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
The number 81 fits into 350 4 times, leaving a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 992.87654
Subtract 324 from 350 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 11:
260 divided by 81 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 992.876543
If we subtract 243 from 260, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
The number 81 fits into 170 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 992.8765432
If we take 162 away from 170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
81 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 992.8765432
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 992.8765432, with a leftover of 8e-08.
