We look at the division of 203618 by 81 
Let's see how many times 81 fits into 203618.

Moving on to step 1:
2 divided by 81 is 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

Let's proceed to step 2:
The number 81 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 81

Going ahead to step 3:
203 divided by 81 is 2 with a remainder of 41.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 162 from 203 leaves us with 41.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 81

Step 4:
416 divided by 81 is 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 405 away from 416, we end up with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 81

On to step 5:
When dividing 111 by 81, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 251.0
Subtracting 81 from 111 leaves us with 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 81

Going ahead to step 6:
81 goes into 308 3 times with a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 2513.0
Subtracting 243 from 308 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 7:
81 goes into 650 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 2513.8
Subtracting 648 from 650 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
81 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 2513.8
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 81 fits into 200 2 times, leaving a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 2513.802
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
380 divided by 81 is 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 2513.8024
The remainder is 56 after subtracting 324 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
81 can be fit into 560 6 times, resulting in a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 2513.80246
Subtracting 486 from 560 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 12:
If we divide 740 by 81, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 2513.802469
If we subtract 729 from 740, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
The number 81 fits into 110 1 times, leaving a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 2513.8024691
If we take 81 away from 110, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 14:
290 divided by 81 is 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 2513.80246913
Subtracting 243 from 290 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Our division results in 2513.80246913 with a remaining 4.7e-08.
