80457 divided by 81 
We want to figure out the number of times 80457 can be divided by 81.

Let's proceed to step 1:
81 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 81

On to step 2:
81 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (4) from the dividend, attach it to 80 and continue: 804 / 81

Moving on to step 3:
The number 81 fits into 804 9 times, leaving a remainder of 75.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 729 from 804 to get 75.
Include the next digit (5) from the dividend after 75, then repeat: 755 / 81

On to step 4:
When dividing 755 by 81, we get 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 99.0
If we take 729 away from 755, we end up with 26.
Include the next digit (7) from the dividend after 26, then repeat: 267 / 81

Moving on to step 5:
If we divide 267 by 81, we get 3 and a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 993.0
Subtract 243 from 267 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 6:
If we divide 240 by 81, we get 2 and a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 993.2
If we take 162 away from 240, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 7:
If we divide 780 by 81, we get 9 and a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 993.29
The remainder is 51 after subtracting 729 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 8:
510 divided by 81 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 993.296
Deduct 486 from 510 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
240 divided by 81 is 2 with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 993.2962
Subtracting 162 from 240 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 10:
The number 81 fits into 780 9 times, leaving a remainder of 51.
The next digit of our result is 9. 
Result so far: 993.29629
Subtracting 729 from 780 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 11:
81 can be fit into 510 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 993.296296
The remainder is 24 after subtracting 486 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
The number 81 fits into 240 2 times, leaving a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 993.2962962
Subtract 162 from 240 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 13:
780 divided by 81 is 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 993.29629629
Deduct 729 from 780 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 993.29629629 with a remainder of 5.1e-08.
