We divide 106831 by 81
We want to figure out the number of times 106831 can be divided by 81.

Advancing to step 1:
81 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 81

Advancing to step 2:
81 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 81

Advancing to step 3:
The number 81 fits into 106 1 times, leaving a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 25 after subtracting 81 from 106.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 81

Let's proceed to step 4:
When dividing 258 by 81, we get 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 243 from 258, we get 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 81

Going ahead to step 5:
The number 81 fits into 153 1 times, leaving a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 131.0
Subtracting 81 from 153 leaves us with 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 81

On to step 6:
The number 81 fits into 721 8 times, leaving a remainder of 73.
Record the quotient 8 as the next digit in the result. 
Result so far: 1318.0
If we subtract 648 from 721, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 7:
The number 81 fits into 730 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 1318.9
Subtracting 729 from 730 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
81 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1318.9
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 81, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1318.901
Subtract 81 from 100 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 10:
190 divided by 81 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 1318.9012
Subtracting 162 from 190 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
280 divided by 81 is 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 1318.90123
The remainder is 37 after subtracting 243 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 12:
When dividing 370 by 81, we get 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 1318.901234
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
81 can be fit into 460 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 1318.9012345
Subtracting 405 from 460 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 14:
The number 81 fits into 550 6 times, leaving a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 1318.90123456
Subtracting 486 from 550 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 1318.90123456 with a remaining 6.4e-08.
