We look at the division of 253166 by 22 
The aim is to understand the frequency of 22 in 253166.

Step 1:
2 divided by 22 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 22

Going ahead to step 2:
If we divide 25 by 22, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 22 from 25, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 22

On to step 3:
33 divided by 22 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 22 from 33 and we're left with 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 22

Advancing to step 4:
If we divide 111 by 22, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
If we subtract 110 from 111, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 22

Advancing to step 5:
22 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 1150.0
Subtract 0 from 16 to get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 22

Going ahead to step 6:
The number 22 fits into 166 7 times, leaving a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 11507.0
Subtracting 154 from 166 leaves us 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 7:
If we divide 120 by 22, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 11507.5
Deduct 110 from 120 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 22, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 11507.54
If we subtract 88 from 100, we 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.

Advancing to step 9:
22 goes into 120 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 11507.545
The remainder is 10 after subtracting 110 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 22 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 11507.5454
Deduct 88 from 100 and we're left 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.

Let's proceed to step 11:
22 goes into 120 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 11507.54545
If we subtract 110 from 120, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
22 can be fit into 100 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 11507.545454
Subtract 88 from 100 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.

Advancing to step 13:
22 can be fit into 120 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 11507.5454545
If we subtract 110 from 120, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
100 divided by 22 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 11507.54545454
If we take 88 away from 100, 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.

Our division results in 11507.54545454 with a remaining 1.2e-08.
