23203553 ÷ 1 
We're looking to find how many times 1 goes into 23203553.

Going ahead to step 1:
1 goes into 2 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 2 from 2.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

On to step 2:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 3 away from 3, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Advancing to step 3:
2 divided by 1 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 232.0
Subtracting 2 from 2 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Advancing to step 4:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 2320.0
Deduct 0 from 0 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

On to step 5:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 23203.0
Subtract 3 from 3 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Let's proceed to step 6:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 232035.0
The remainder is 0 after subtracting 5 from 5.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Going ahead to step 7:
When dividing 5 by 1, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2320355.0
Subtract 5 from 5 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Step 8:
When dividing 3 by 1, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 23203553.0
If we subtract 3 from 3, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23203553.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 23203553.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 23203553.0, and the remainder is 0.0.
