We divide 163821 by 81
Our goal is to divide 163821 by 81.

Moving on to step 1:
81 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 81

Let's proceed to step 2:
81 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 81

On to step 3:
If we divide 163 by 81, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 162 from 163 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 81

Let's proceed to step 4:
The number 81 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtract 0 from 18 to get 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 81

Moving on to step 5:
The number 81 fits into 182 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 202.0
If we take 162 away from 182, we end up with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 81

Advancing to step 6:
When dividing 201 by 81, we get 2 with a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 2022.0
Deduct 162 from 201 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.

Moving on to step 7:
If we divide 390 by 81, we get 4 and a remainder of 66.
The next digit of our result is 4. 
Result so far: 2022.4
If we subtract 324 from 390, we 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.

On to step 8:
81 can be fit into 660 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 2022.48
Subtract 648 from 660 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
If we divide 120 by 81, we get 1 and a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 2022.481
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.

Let's proceed to step 10:
81 can be fit into 390 4 times, resulting in a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 2022.4814
The remainder is 66 after subtracting 324 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
660 divided by 81 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 2022.48148
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.

Let's proceed to step 12:
When dividing 120 by 81, we get 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 2022.481481
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.

Let's proceed to step 13:
81 can be fit into 390 4 times, resulting in a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 2022.4814814
If we take 324 away from 390, we end up 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 14:
81 goes into 660 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 2022.48148148
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.

In conclusion, the division gives 2022.48148148 with a balance of 1.2e-08.
