Let's divide 20003 by 81
We want to divide 20003 by 81.

Going ahead to step 1:
When dividing 2 by 81, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 81

On to step 2:
When dividing 20 by 81, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 81

Let's proceed to step 3:
If we divide 200 by 81, we get 2 and a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 38 after subtracting 162 from 200.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 81

Going ahead to step 4:
When dividing 380 by 81, we get 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtract 324 from 380 to get 56.
Fetch the next digit (3) from the dividend, attach it to 56 and continue: 563 / 81

On to step 5:
81 can be fit into 563 6 times, resulting in a remainder of 77.
Use 6 as the next digit of our solution. 
Result so far: 246.0
If we subtract 486 from 563, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 6:
81 goes into 770 9 times with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 246.9
The remainder is 41 after subtracting 729 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
410 divided by 81 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 246.95
The remainder is 5 after subtracting 405 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
81 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 246.95
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
81 can be fit into 500 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 246.9506
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
81 can be fit into 140 1 times, resulting in a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 246.95061
The remainder is 59 after subtracting 81 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 11:
If we divide 590 by 81, we get 7 and a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 246.950617
If we subtract 567 from 590, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
81 goes into 230 2 times with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 246.9506172
Subtract 162 from 230 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 13:
680 divided by 81 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 246.95061728
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 246.95061728, and the remainder is 3.2e-08.
