We're dividing 23010503 by 809 
We want to figure out the number of times 23010503 can be divided by 809.

Moving on to step 1:
If we divide 2 by 809, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 809

On to step 2:
If we divide 23 by 809, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Append the next digit (0) from the dividend to 23 and continue with: 230 / 809

On to step 3:
The number 809 fits into 230 0 times, leaving a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 230 after subtracting 0 from 230.
Include the next digit (1) from the dividend after 230, then repeat: 2301 / 809

On to step 4:
The number 809 fits into 2301 2 times, leaving a remainder of 683.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1618 from 2301 and we're left with 683.
Bring next digit (0) of the dividend behind the 683 and repeat the process: 6830 / 809

Advancing to step 5:
If we divide 6830 by 809, we get 8 and a remainder of 358.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 6472 from 6830 and we're left with 358.
Include the next digit (5) from the dividend after 358, then repeat: 3585 / 809

Advancing to step 6:
If we divide 3585 by 809, we get 4 and a remainder of 349.
Put 4 as the next digit of the answer. 
Result so far: 284.0
If we subtract 3236 from 3585, we get 349.
Fetch the next digit (0) from the dividend, attach it to 349 and continue: 3490 / 809

Let's proceed to step 7:
When dividing 3490 by 809, we get 4 with a remainder of 254.
Record the quotient 4 as the next digit in the result. 
Result so far: 2844.0
Subtract 3236 from 3490 to get 254.
Append the next digit (3) from the dividend to 254 and continue with: 2543 / 809

Step 8:
2543 divided by 809 is 3 with a remainder of 116.
Use 3 as the next digit of our solution. 
Result so far: 28443.0
Subtract 2427 from 2543 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 9:
809 goes into 1160 1 times with a remainder of 351.
Put 1 as the next digit of the answer. 
Result so far: 28443.1
Deduct 809 from 1160 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 10:
809 can be fit into 3510 4 times, resulting in a remainder of 274.
Use 4 as the next digit of our solution. 
Result so far: 28443.14
The remainder is 274 after subtracting 3236 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 11:
809 can be fit into 2740 3 times, resulting in a remainder of 313.
Use 3 as the next digit of our solution. 
Result so far: 28443.143
If we subtract 2427 from 2740, we get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

On to step 12:
When dividing 3130 by 809, we get 3 with a remainder of 703.
Record the quotient 3 as the next digit in the result. 
Result so far: 28443.1433
Subtracting 2427 from 3130 leaves us with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

The quotient of the division is 28443.1433, and the remainder is 0.00703.
