We divide 497635 by 28
The aim is to understand the frequency of 28 in 497635.

Step 1:
The number 28 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 28

Step 2:
The number 28 fits into 49 1 times, leaving a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 28 from 49 leaves us with 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 28

On to step 3:
28 can be fit into 217 7 times, resulting in a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 21 after subtracting 196 from 217.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 28

Let's proceed to step 4:
28 can be fit into 216 7 times, resulting in a remainder of 20.
The next digit of our result is 7. 
Result so far: 177.0
If we take 196 away from 216, we end up with 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 28

Moving on to step 5:
203 divided by 28 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 1777.0
If we subtract 196 from 203, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 28

Let's proceed to step 6:
75 divided by 28 is 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 17772.0
If we subtract 56 from 75, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
If we divide 190 by 28, we get 6 and a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 17772.6
Subtract 168 from 190 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
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: 17772.67
The remainder is 24 after subtracting 196 from 220.
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 9:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 17772.678
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.

Moving on to step 10:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 17772.6785
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.

Advancing to step 11:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 17772.67857
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.

Step 12:
28 goes into 40 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 17772.678571
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.

Going ahead to step 13:
When dividing 120 by 28, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 17772.6785714
If we take 112 away from 120, we end up 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.

On to step 14:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 17772.67857142
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.

The quotient of the division is 17772.67857142, and the remainder is 2.4e-08.
