303151 divided by 78 
We're looking to find how many times 78 goes into 303151.

Moving on to step 1:
78 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 78

Moving on to step 2:
78 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 78

Let's proceed to step 3:
303 divided by 78 is 3 with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 69 after subtracting 234 from 303.
Take the next digit (1) from the dividend and append it to 69, then repeat: 691 / 78

Moving on to step 4:
When dividing 691 by 78, we get 8 with a remainder of 67.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtracting 624 from 691 leaves us with 67.
Bring next digit (5) of the dividend behind the 67 and repeat the process: 675 / 78

Let's proceed to step 5:
78 can be fit into 675 8 times, resulting in a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 388.0
Deduct 624 from 675 and we're left with 51.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 78

Going ahead to step 6:
When dividing 511 by 78, we get 6 with a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 3886.0
Deduct 468 from 511 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
78 can be fit into 430 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 3886.5
Deduct 390 from 430 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3886.55
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 3886.55 with a remaining 0.01.
