112780 ÷ 28 
The aim is to understand the frequency of 28 in 112780.

Step 1:
28 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 28

Moving on to step 2:
The number 28 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 28

Advancing to step 3:
If we divide 112 by 28, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 112 from 112, we get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 28

Going ahead to step 4:
If we divide 7 by 28, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 28

Let's proceed to step 5:
78 divided by 28 is 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 402.0
Deduct 56 from 78 and we're left with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 28

Let's proceed to step 6:
When dividing 220 by 28, we get 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 4027.0
Deduct 196 from 220 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.

Going ahead to step 7:
28 goes into 240 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 4027.8
If we take 224 away from 240, we end up 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.

Going ahead to step 8:
28 goes into 160 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 4027.85
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 4027.857
If we subtract 196 from 200, we get 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 10:
When dividing 40 by 28, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 4027.8571
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
When dividing 120 by 28, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4027.85714
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
If we divide 80 by 28, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 4027.857142
Subtracting 56 from 80 leaves us 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.

On to step 13:
28 goes into 240 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 4027.8571428
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
160 divided by 28 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 4027.85714285
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 4027.85714285 with a remainder of 2e-08.
