819668 ÷ 81 
Our goal is to divide 819668 by 81.

Let's proceed to step 1:
If we divide 8 by 81, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 81

Step 2:
When dividing 81 by 81, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 81 from 81 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 81

Step 3:
9 divided by 81 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 81

Step 4:
If we divide 96 by 81, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Deduct 81 from 96 and we're left with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 81

Step 5:
81 goes into 156 1 times with a remainder of 75.
Use 1 as the next digit of our solution. 
Result so far: 1011.0
Subtract 81 from 156 to get 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 81

Step 6:
81 goes into 758 9 times with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 10119.0
If we take 729 away from 758, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
The number 81 fits into 290 3 times, leaving a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 10119.3
The remainder is 47 after subtracting 243 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 8:
The number 81 fits into 470 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 10119.35
Subtract 405 from 470 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
When dividing 650 by 81, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 10119.358
The remainder is 2 after subtracting 648 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
81 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10119.358
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
If we divide 200 by 81, we get 2 and a remainder of 38.
The next digit of our result is 2. 
Result so far: 10119.35802
If we subtract 162 from 200, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
If we divide 380 by 81, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 10119.358024
Subtract 324 from 380 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
81 goes into 560 6 times with a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 10119.3580246
If we take 486 away from 560, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 14:
The number 81 fits into 740 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 10119.35802469
If we take 729 away from 740, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 10119.35802469, with a leftover of 1.1e-08.
