We look at the division of 28956 by 78 
The aim is to understand the frequency of 78 in 28956.

On to step 1:
When dividing 2 by 78, we get 0 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.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 78

On to step 2:
The number 78 fits into 28 0 times, leaving a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 78

Advancing to step 3:
When dividing 289 by 78, we get 3 with a remainder of 55.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 234 from 289, we get 55.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 78

Step 4:
When dividing 555 by 78, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 546 from 555, we get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 78

Let's proceed to step 5:
The number 78 fits into 96 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 371.0
Subtract 78 from 96 to get 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 6:
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: 371.2
Deduct 156 from 180 and we're left with 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 7:
78 can be fit into 240 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 371.23
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.

Let's proceed to step 8:
78 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 371.23
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.

Moving on to step 9:
If we divide 600 by 78, we get 7 and a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 371.2307
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.

Step 10:
540 divided by 78 is 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 371.23076
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
78 can be fit into 720 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 371.230769
Subtracting 702 from 720 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 12:
When dividing 180 by 78, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 371.2307692
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
240 divided by 78 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 371.23076923
If we take 234 away from 240, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 371.23076923 and a remainder of 6e-09.
