We divide 203636 by 21
Let's see how many times 21 fits into 203636.

Let's proceed to step 1:
21 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 21

Moving on to step 2:
If we divide 20 by 21, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 21

Advancing to step 3:
203 divided by 21 is 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 189 from 203, we get 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 21

Advancing to step 4:
21 goes into 146 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 96.0
Subtracting 126 from 146 leaves us with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 21

Let's proceed to step 5:
The number 21 fits into 203 9 times, leaving a remainder of 14.
The next digit of our result is 9. 
Result so far: 969.0
Deduct 189 from 203 and we're left with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 21

Advancing to step 6:
21 can be fit into 146 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 9696.0
The remainder is 20 after subtracting 126 from 146.
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 7:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 9696.9
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 8:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 9696.95
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
If we divide 50 by 21, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 9696.952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
21 goes into 80 3 times with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 9696.9523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 11:
170 divided by 21 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 9696.95238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9696.95238
The remainder is 20 after subtracting 0 from 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 13:
200 divided by 21 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 9696.9523809
Subtract 189 from 200 to 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.

Step 14:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 9696.95238095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 9696.95238095 and a remainder of 5e-09.
