We look at the division of 672563 by 28 
The aim is to understand the frequency of 28 in 672563.

Moving on to step 1:
6 divided by 28 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 28

Let's proceed to step 2:
If we divide 67 by 28, we get 2 and a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 56 from 67 leaves us with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 28

On to step 3:
112 divided by 28 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 112 from 112 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 28

Advancing to step 4:
5 divided by 28 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 240.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 28

Let's proceed to step 5:
28 can be fit into 56 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2402.0
Deduct 56 from 56 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 28

Going ahead to step 6:
28 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 24020.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
When dividing 30 by 28, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 24020.1
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 28 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 24020.1
If we take 0 away from 20, we end up 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.

Step 9:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 24020.107
The remainder is 4 after subtracting 196 from 200.
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:
If we divide 40 by 28, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 24020.1071
If we take 28 away from 40, we end up 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.

Let's proceed to step 11:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 24020.10714
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:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 24020.107142
Subtract 56 from 80 to get 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: 24020.1071428
The remainder is 16 after subtracting 224 from 240.
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:
When dividing 160 by 28, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 24020.10714285
Subtracting 140 from 160 leaves us 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 quotient of the division is 24020.10714285, and the remainder is 2e-08.
