Let's divide 798636 by 28
The aim is to understand the frequency of 28 in 798636.

Step 1:
28 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 28

Advancing to step 2:
When dividing 79 by 28, we get 2 with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 56 from 79 leaves us with 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 28

Going ahead to step 3:
When dividing 238 by 28, we get 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 224 from 238 and we're left with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 28

Advancing to step 4:
The number 28 fits into 146 5 times, leaving a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 285.0
Subtracting 140 from 146 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 28

Going ahead to step 5:
The number 28 fits into 63 2 times, leaving a remainder of 7.
The next digit of our result is 2. 
Result so far: 2852.0
Subtracting 56 from 63 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 28

Let's proceed to step 6:
The number 28 fits into 76 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 28522.0
If we subtract 56 from 76, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
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: 28522.7
If we take 196 away from 200, 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.

On to step 8:
40 divided by 28 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 28522.71
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 28522.714
Subtracting 112 from 120 leaves us with 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 10:
80 divided by 28 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 28522.7142
Deduct 56 from 80 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 11:
28 goes into 240 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 28522.71428
Subtracting 224 from 240 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 12:
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: 28522.714285
Subtract 140 from 160 to get 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 13:
When dividing 200 by 28, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 28522.7142857
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.

Advancing to step 14:
When dividing 40 by 28, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 28522.71428571
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.

After the division, we end up with 28522.71428571 and a remainder of 1.2e-08.
