We're dividing 259287 by 22 
The aim is to understand the frequency of 22 in 259287.

Step 1:
If we divide 2 by 22, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 22

Step 2:
When dividing 25 by 22, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 22 from 25 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 22

On to step 3:
The number 22 fits into 39 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 22 from 39, we get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 22

Step 4:
22 goes into 172 7 times with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
If we subtract 154 from 172, we get 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 22

On to step 5:
When dividing 188 by 22, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1178.0
Subtracting 176 from 188 leaves us with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 22

Going ahead to step 6:
127 divided by 22 is 5 with a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 11785.0
Subtract 110 from 127 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
22 can be fit into 170 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 11785.7
Deduct 154 from 170 and we're left 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.

Moving on to step 8:
22 goes into 160 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 11785.77
The remainder is 6 after subtracting 154 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 11785.77 with a remaining 0.006.
