We're dividing 830311 by 81 
We're looking to find how many times 81 goes into 830311.

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
Subtracting 0 from 8 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 81

Going ahead to step 2:
81 can be fit into 83 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 81 from 83, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 81

Advancing to step 3:
81 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 20, we end up with 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 81

Moving on to step 4:
81 goes into 203 2 times with a remainder of 41.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtract 162 from 203 to get 41.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 81

Advancing to step 5:
81 goes into 411 5 times with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 1025.0
If we take 405 away from 411, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 81

Step 6:
81 can be fit into 61 0 times, resulting in a remainder of 61.
The next digit of our result is 0. 
Result so far: 10250.0
If we subtract 0 from 61, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 7:
If we divide 610 by 81, we get 7 and a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 10250.7
If we take 567 away from 610, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 8:
The number 81 fits into 430 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 10250.75
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
81 goes into 250 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 10250.753
Deduct 243 from 250 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
81 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 10250.753
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
81 goes into 700 8 times with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 10250.75308
If we subtract 648 from 700, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
The number 81 fits into 520 6 times, leaving a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 10250.753086
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
81 goes into 340 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 10250.7530864
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
160 divided by 81 is 1 with a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 10250.75308641
Subtract 81 from 160 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Our division results in 10250.75308641 with a remaining 7.9e-08.
