382129 ÷ 78 
The aim is to understand the frequency of 78 in 382129.

Going ahead to step 1:
78 can be fit into 3 0 times, resulting in 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.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 78

Advancing to step 2:
78 can be fit into 38 0 times, resulting in a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (2) from the dividend after 38, then repeat: 382 / 78

Step 3:
When dividing 382 by 78, we get 4 with a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 312 from 382, we get 70.
Bring next digit (1) of the dividend behind the 70 and repeat the process: 701 / 78

Let's proceed to step 4:
78 goes into 701 8 times with a remainder of 77.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 624 from 701 to get 77.
Include the next digit (2) from the dividend after 77, then repeat: 772 / 78

Advancing to step 5:
772 divided by 78 is 9 with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 489.0
Subtract 702 from 772 to get 70.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 78

On to step 6:
When dividing 709 by 78, we get 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 4899.0
Subtract 702 from 709 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
78 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 4899.0
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 4899.08
If we subtract 624 from 700, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
If we divide 760 by 78, we get 9 and a remainder of 58.
The next digit of our result is 9. 
Result so far: 4899.089
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 4899.0897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
78 goes into 340 4 times with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 4899.08974
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
The number 78 fits into 280 3 times, leaving a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 4899.089743
The remainder is 46 after subtracting 234 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
78 goes into 460 5 times with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 4899.0897435
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 4899.08974358
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 4899.08974358 with a remaining 7.6e-08.
