330630 ÷ 78 
The aim is to understand the frequency of 78 in 330630.

Advancing to step 1:
3 divided by 78 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 78

Going ahead to step 2:
78 goes into 33 0 times with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 78

Let's proceed to step 3:
The number 78 fits into 330 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 312 from 330 to get 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 78

On to step 4:
When dividing 186 by 78, we get 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Deduct 156 from 186 and we're left with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 78

Going ahead to step 5:
78 goes into 303 3 times with a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 423.0
If we take 234 away from 303, we end up with 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 78

Step 6:
78 can be fit into 690 8 times, resulting in a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 4238.0
Subtract 624 from 690 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 7:
78 can be fit into 660 8 times, resulting in a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 4238.8
Deduct 624 from 660 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
When dividing 360 by 78, we get 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 4238.84
The remainder is 48 after subtracting 312 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
If we divide 480 by 78, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 4238.846
Subtracting 468 from 480 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
78 goes into 120 1 times with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 4238.8461
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 4238.84615
If we take 390 away from 420, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
300 divided by 78 is 3 with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 4238.846153
If we subtract 234 from 300, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
660 divided by 78 is 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 4238.8461538
The remainder is 36 after subtracting 624 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
360 divided by 78 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 4238.84615384
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 4238.84615384 with a balance of 4.8e-08.
