65099543 ÷ 900 
Our goal is to divide 65099543 by 900.

Going ahead to step 1:
When dividing 6 by 900, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 900

Advancing to step 2:
If we divide 65 by 900, we get 0 and a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Fetch the next digit (0) from the dividend, attach it to 65 and continue: 650 / 900

On to step 3:
650 divided by 900 is 0 with a remainder of 650.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 650 after subtracting 0 from 650.
Take the next digit (9) from the dividend and append it to 650, then repeat: 6509 / 900

Let's proceed to step 4:
6509 divided by 900 is 7 with a remainder of 209.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 209 after subtracting 6300 from 6509.
Include the next digit (9) from the dividend after 209, then repeat: 2099 / 900

Let's proceed to step 5:
When dividing 2099 by 900, we get 2 with a remainder of 299.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtract 1800 from 2099 to get 299.
Include the next digit (5) from the dividend after 299, then repeat: 2995 / 900

Step 6:
When dividing 2995 by 900, we get 3 with a remainder of 295.
The next digit of our result is 3. 
Result so far: 723.0
If we subtract 2700 from 2995, we get 295.
Take the next digit (4) from the dividend and append it to 295, then repeat: 2954 / 900

Advancing to step 7:
If we divide 2954 by 900, we get 3 and a remainder of 254.
The next digit of our result is 3. 
Result so far: 7233.0
If we take 2700 away from 2954, we end up with 254.
Include the next digit (3) from the dividend after 254, then repeat: 2543 / 900

On to step 8:
When dividing 2543 by 900, we get 2 with a remainder of 743.
The next digit of our result is 2. 
Result so far: 72332.0
If we subtract 1800 from 2543, we get 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Let's proceed to step 9:
When dividing 7430 by 900, we get 8 with a remainder of 230.
Record the quotient 8 as the next digit in the result. 
Result so far: 72332.8
If we subtract 7200 from 7430, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 10:
2300 divided by 900 is 2 with a remainder of 500.
Write down 2 as next digit of the result. 
Result so far: 72332.82
Subtracting 1800 from 2300 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 11:
900 goes into 5000 5 times with a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 72332.825
If we subtract 4500 from 5000, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 12:
900 goes into 5000 5 times with a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 72332.8255
If we take 4500 away from 5000, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final outcome is 72332.8255, with a leftover of 0.005.
