We divide 800790 by 81
Our goal is to divide 800790 by 81.

Moving on to step 1:
If we divide 8 by 81, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 81

Moving on to step 2:
81 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (0) of the dividend behind the 80 and repeat the process: 800 / 81

Step 3:
When dividing 800 by 81, we get 9 with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 71 after subtracting 729 from 800.
Fetch the next digit (7) from the dividend, attach it to 71 and continue: 717 / 81

Advancing to step 4:
81 can be fit into 717 8 times, resulting in a remainder of 69.
Write down 8 as next digit of the result. 
Result so far: 98.0
Subtract 648 from 717 to get 69.
Fetch the next digit (9) from the dividend, attach it to 69 and continue: 699 / 81

Step 5:
81 can be fit into 699 8 times, resulting in a remainder of 51.
The next digit of our result is 8. 
Result so far: 988.0
If we subtract 648 from 699, we get 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 81

Going ahead to step 6:
If we divide 510 by 81, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 9886.0
If we subtract 486 from 510, we 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.

Step 7:
When dividing 240 by 81, we get 2 with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 9886.2
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.

Advancing to step 8:
81 can be fit into 780 9 times, resulting in a remainder of 51.
The next digit of our result is 9. 
Result so far: 9886.29
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.

Going ahead to step 9:
If we divide 510 by 81, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 9886.296
Subtract 486 from 510 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.

Let's proceed to step 10:
When dividing 240 by 81, we get 2 with a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 9886.2962
Deduct 162 from 240 and we're left 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.

On to step 11:
The number 81 fits into 780 9 times, leaving a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 9886.29629
If we subtract 729 from 780, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 12:
510 divided by 81 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 9886.296296
If we take 486 away from 510, we end up 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.

Step 13:
The number 81 fits into 240 2 times, leaving a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 9886.2962962
The remainder is 78 after subtracting 162 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 14:
The number 81 fits into 780 9 times, leaving a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 9886.29629629
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.

After the division, we end up with 9886.29629629 and a remainder of 5.1e-08.
