We're dividing 270880 by 78 
The aim is to understand the frequency of 78 in 270880.

Step 1:
78 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 78

Going ahead to step 2:
The number 78 fits into 27 0 times, leaving a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 78

On to step 3:
The number 78 fits into 270 3 times, leaving a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 36 after subtracting 234 from 270.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 78

On to step 4:
78 can be fit into 368 4 times, resulting in a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 312 from 368 and we're left with 56.
Bring next digit (8) of the dividend behind the 56 and repeat the process: 568 / 78

Going ahead to step 5:
If we divide 568 by 78, we get 7 and a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 347.0
The remainder is 22 after subtracting 546 from 568.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 78

Let's proceed to step 6:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 3472.0
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
640 divided by 78 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3472.8
Deduct 624 from 640 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
160 divided by 78 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 3472.82
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 78 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3472.82
Subtracting 0 from 40 leaves us 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.

Let's proceed to step 10:
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: 3472.8205
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.

Advancing to step 11:
78 goes into 100 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 3472.82051
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
The number 78 fits into 220 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 3472.820512
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
If we divide 640 by 78, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3472.8205128
Subtracting 624 from 640 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
If we divide 160 by 78, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 3472.82051282
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 3472.82051282 with a remainder of 4e-09.
