We're dividing 302970 by 78 
Let's see how many times 78 fits into 302970.

Step 1:
When dividing 3 by 78, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 78

Going ahead to step 2:
30 divided by 78 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Append the next digit (2) from the dividend to 30 and continue with: 302 / 78

Let's proceed to step 3:
78 goes into 302 3 times with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 68 after subtracting 234 from 302.
Bring next digit (9) of the dividend behind the 68 and repeat the process: 689 / 78

Advancing to step 4:
689 divided by 78 is 8 with a remainder of 65.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we take 624 away from 689, we end up with 65.
Fetch the next digit (7) from the dividend, attach it to 65 and continue: 657 / 78

Going ahead to step 5:
When dividing 657 by 78, we get 8 with a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 388.0
Subtract 624 from 657 to get 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 78

Let's proceed to step 6:
When dividing 330 by 78, we get 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 3884.0
Subtracting 312 from 330 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
When dividing 180 by 78, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 3884.2
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
When dividing 240 by 78, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3884.23
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 3884.23
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
600 divided by 78 is 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 3884.2307
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 11:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 3884.23076
If we take 468 away from 540, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
When dividing 720 by 78, we get 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 3884.230769
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
78 can be fit into 180 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 3884.2307692
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 14:
78 can be fit into 240 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 3884.23076923
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 3884.23076923 with a remainder of 6e-09.
