Let's divide 78255109 by 300
We want to divide 78255109 by 300.

Moving on to step 1:
If we divide 7 by 300, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 300

Moving on to step 2:
The number 300 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 300

Moving on to step 3:
If we divide 782 by 300, we get 2 and a remainder of 182.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 600 from 782 and we're left with 182.
Take the next digit (5) from the dividend and append it to 182, then repeat: 1825 / 300

Going ahead to step 4:
When dividing 1825 by 300, we get 6 with a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we take 1800 away from 1825, we end up with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 300

Step 5:
300 can be fit into 255 0 times, resulting in a remainder of 255.
The number 0 becomes the next digit in our result. 
Result so far: 260.0
The remainder is 255 after subtracting 0 from 255.
Fetch the next digit (1) from the dividend, attach it to 255 and continue: 2551 / 300

Step 6:
300 can be fit into 2551 8 times, resulting in a remainder of 151.
The number 8 becomes the next digit in our result. 
Result so far: 2608.0
Subtract 2400 from 2551 to get 151.
Include the next digit (0) from the dividend after 151, then repeat: 1510 / 300

Let's proceed to step 7:
When dividing 1510 by 300, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 26085.0
The remainder is 10 after subtracting 1500 from 1510.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 300

On to step 8:
When dividing 109 by 300, we get 0 with a remainder of 109.
Record the quotient 0 as the next digit in the result. 
Result so far: 260850.0
The remainder is 109 after subtracting 0 from 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 9:
The number 300 fits into 1090 3 times, leaving a remainder of 190.
Write down 3 as next digit of the result. 
Result so far: 260850.3
If we take 900 away from 1090, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
The number 300 fits into 1900 6 times, leaving a remainder of 100.
Put 6 as the next digit of the answer. 
Result so far: 260850.36
If we subtract 1800 from 1900, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
If we divide 1000 by 300, we get 3 and a remainder of 100.
The next digit of our result is 3. 
Result so far: 260850.363
Deduct 900 from 1000 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 12:
If we divide 1000 by 300, we get 3 and a remainder of 100.
Put 3 as the next digit of the answer. 
Result so far: 260850.3633
Subtracting 900 from 1000 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 260850.3633 with a remaining 0.001.
