Let's divide 301509 by 78
Our goal is to divide 301509 by 78.

Let's proceed to step 1:
3 divided by 78 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 78

Advancing to step 2:
If we divide 30 by 78, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 78

On to step 3:
78 can be fit into 301 3 times, resulting in a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 234 from 301 and we're left with 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 78

Step 4:
78 goes into 675 8 times with a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 38.0
Deduct 624 from 675 and we're left with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 78

Let's proceed to step 5:
The number 78 fits into 510 6 times, leaving a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 386.0
Subtracting 468 from 510 leaves us with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 78

Step 6:
When dividing 429 by 78, we get 5 with a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 3865.0
If we subtract 390 from 429, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
78 goes into 390 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3865.5
Deduct 390 from 390 and we're left 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.

Going ahead to step 8:
0 divided by 78 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3865.5
Subtract 0 from 0 to 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.

Advancing to step 9:
The number 78 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3865.5
If we subtract 0 from 0, 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.

In conclusion, the division gives 3865.5 with a balance of 0.0.
