We look at the division of 20090353 by 818 
We're looking to find how many times 818 goes into 20090353.

Let's proceed to step 1:
When dividing 2 by 818, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 818

Moving on to step 2:
When dividing 20 by 818, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 818

Step 3:
When dividing 200 by 818, we get 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 200 to get 200.
Include the next digit (9) from the dividend after 200, then repeat: 2009 / 818

Let's proceed to step 4:
The number 818 fits into 2009 2 times, leaving a remainder of 373.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 373 after subtracting 1636 from 2009.
Include the next digit (0) from the dividend after 373, then repeat: 3730 / 818

Let's proceed to step 5:
If we divide 3730 by 818, we get 4 and a remainder of 458.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 458 after subtracting 3272 from 3730.
Grab the next digit (3) from the dividend, add it to 458, then carry on: 4583 / 818

Moving on to step 6:
818 goes into 4583 5 times with a remainder of 493.
The next digit of our result is 5. 
Result so far: 245.0
Subtracting 4090 from 4583 leaves us with 493.
Append the next digit (5) from the dividend to 493 and continue with: 4935 / 818

Going ahead to step 7:
If we divide 4935 by 818, we get 6 and a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 2456.0
Deduct 4908 from 4935 and we're left with 27.
Include the next digit (3) from the dividend after 27, then repeat: 273 / 818

Step 8:
818 can be fit into 273 0 times, resulting in a remainder of 273.
Put 0 as the next digit of the answer. 
Result so far: 24560.0
If we subtract 0 from 273, we get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Advancing to step 9:
If we divide 2730 by 818, we get 3 and a remainder of 276.
The next digit of our result is 3. 
Result so far: 24560.3
The remainder is 276 after subtracting 2454 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 10:
818 can be fit into 2760 3 times, resulting in a remainder of 306.
Use 3 as the next digit of our solution. 
Result so far: 24560.33
If we subtract 2454 from 2760, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

The final outcome is 24560.33, with a leftover of 0.306.
