Let's divide 231456 by 81
We want to figure out the number of times 231456 can be divided by 81.

On to step 1:
The number 81 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 81

On to step 2:
If we divide 23 by 81, we get 0 and a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 81

Let's proceed to step 3:
If we divide 231 by 81, we get 2 and a remainder of 69.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 162 away from 231, we end up with 69.
Fetch the next digit (4) from the dividend, attach it to 69 and continue: 694 / 81

Going ahead to step 4:
81 can be fit into 694 8 times, resulting in a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtract 648 from 694 to get 46.
Fetch the next digit (5) from the dividend, attach it to 46 and continue: 465 / 81

Step 5:
465 divided by 81 is 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 285.0
Subtract 405 from 465 to get 60.
Include the next digit (6) from the dividend after 60, then repeat: 606 / 81

Moving on to step 6:
606 divided by 81 is 7 with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 2857.0
If we subtract 567 from 606, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
The number 81 fits into 390 4 times, leaving a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 2857.4
Subtract 324 from 390 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 8:
When dividing 660 by 81, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 2857.48
Deduct 648 from 660 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
If we divide 120 by 81, we get 1 and a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 2857.481
Deduct 81 from 120 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 10:
390 divided by 81 is 4 with a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 2857.4814
Subtracting 324 from 390 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
660 divided by 81 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 2857.48148
If we take 648 away from 660, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
81 goes into 120 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 2857.481481
Deduct 81 from 120 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 13:
The number 81 fits into 390 4 times, leaving a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 2857.4814814
Deduct 324 from 390 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 14:
When dividing 660 by 81, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 2857.48148148
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 2857.48148148, and the remainder is 1.2e-08.
