We're dividing 288589 by 28 
The aim is to understand the frequency of 28 in 288589.

Moving on to step 1:
When dividing 2 by 28, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 28

Advancing to step 2:
When dividing 28 by 28, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 28 from 28.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 28

Advancing to step 3:
8 divided by 28 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 28

Let's proceed to step 4:
If we divide 85 by 28, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Deduct 84 from 85 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 28

Let's proceed to step 5:
28 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 1030.0
If we subtract 0 from 18, we get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 28

Advancing to step 6:
The number 28 fits into 189 6 times, leaving a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 10306.0
If we take 168 away from 189, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
The number 28 fits into 210 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 10306.7
Deduct 196 from 210 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
28 goes into 140 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10306.75
Deduct 140 from 140 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 28 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10306.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 28 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10306.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 10306.75, and the remainder is 0.0.
