We divide 831230 by 81
Let's see how many times 81 fits into 831230.

Let's proceed to step 1:
The number 81 fits into 8 0 times, leaving 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.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 81

On to step 2:
81 can be fit into 83 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 81 from 83 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 81

On to step 3:
21 divided by 81 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 21, we get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 81

Moving on to step 4:
212 divided by 81 is 2 with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
If we subtract 162 from 212, we get 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 81

Moving on to step 5:
81 goes into 503 6 times with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 1026.0
If we subtract 486 from 503, we get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 81

Going ahead to step 6:
170 divided by 81 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 10262.0
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.

Step 7:
80 divided by 81 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 10262.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
800 divided by 81 is 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 10262.09
If we take 729 away from 800, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 9:
81 goes into 710 8 times with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 10262.098
If we subtract 648 from 710, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
If we divide 620 by 81, we get 7 and a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 10262.0987
If we subtract 567 from 620, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 11:
81 goes into 530 6 times with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 10262.09876
Subtracting 486 from 530 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
81 can be fit into 440 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 10262.098765
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
If we divide 350 by 81, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 10262.0987654
If we take 324 away from 350, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
81 can be fit into 260 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 10262.09876543
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 10262.09876543 and a remainder of 1.7e-08.
