Let's divide 999089 by 28
The aim is to understand the frequency of 28 in 999089.

Moving on to step 1:
When dividing 9 by 28, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 28

On to step 2:
The number 28 fits into 99 3 times, leaving a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 84 away from 99, we end up with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 28

On to step 3:
28 can be fit into 159 5 times, resulting in a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Deduct 140 from 159 and we're left with 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 28

Moving on to step 4:
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: 356.0
If we subtract 168 from 190, we get 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 28

Step 5:
When dividing 228 by 28, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 3568.0
If we take 224 away from 228, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 28

Moving on to step 6:
The number 28 fits into 49 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 35681.0
If we subtract 28 from 49, we get 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:
When dividing 210 by 28, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 35681.7
The remainder is 14 after subtracting 196 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
140 divided by 28 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 35681.75
Subtracting 140 from 140 leaves us 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.

Advancing to step 9:
28 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 35681.75
If we take 0 away from 0, we end up 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.

On to step 10:
0 divided by 28 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 35681.75
Subtracting 0 from 0 leaves us 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.

The final result is 35681.75 with a remainder of 0.0.
