21303303 ÷ 206 
We want to figure out the number of times 21303303 can be divided by 206.

On to step 1:
206 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 206

Going ahead to step 2:
The number 206 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 206

Step 3:
If we divide 213 by 206, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 206 from 213 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 206

Moving on to step 4:
When dividing 70 by 206, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 70, we get 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 206

Let's proceed to step 5:
The number 206 fits into 703 3 times, leaving a remainder of 85.
The next digit of our result is 3. 
Result so far: 103.0
Subtract 618 from 703 to get 85.
Include the next digit (3) from the dividend after 85, then repeat: 853 / 206

Step 6:
The number 206 fits into 853 4 times, leaving a remainder of 29.
The next digit of our result is 4. 
Result so far: 1034.0
If we subtract 824 from 853, we get 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 206

Going ahead to step 7:
When dividing 290 by 206, we get 1 with a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 10341.0
The remainder is 84 after subtracting 206 from 290.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 206

Step 8:
206 can be fit into 843 4 times, resulting in a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 103414.0
If we take 824 away from 843, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
206 can be fit into 190 0 times, resulting in a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 103414.0
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 10:
206 can be fit into 1900 9 times, resulting in a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 103414.09
Deduct 1854 from 1900 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
206 goes into 460 2 times with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 103414.092
If we take 412 away from 460, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
206 can be fit into 480 2 times, resulting in a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 103414.0922
Deduct 412 from 480 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 103414.0922 with a remaining 0.00068.
