We look at the division of 426406 by 22 
The aim is to understand the frequency of 22 in 426406.

Step 1:
The number 22 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 22

Moving on to step 2:
22 goes into 42 1 times with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 22 from 42 to get 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 22

Let's proceed to step 3:
206 divided by 22 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 198 from 206, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 22

Going ahead to step 4:
22 can be fit into 84 3 times, resulting in a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 193.0
Subtract 66 from 84 to get 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 22

Moving on to step 5:
The number 22 fits into 180 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 1938.0
Subtract 176 from 180 to get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 22

Step 6:
When dividing 46 by 22, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 19382.0
If we subtract 44 from 46, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
The number 22 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 19382.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 22 fits into 200 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 19382.09
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
20 divided by 22 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 19382.09
If we subtract 0 from 20, we 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.

Step 10:
When dividing 200 by 22, we get 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 19382.0909
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
22 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 19382.0909
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
22 goes into 200 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 19382.090909
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
If we divide 20 by 22, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 19382.090909
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
200 divided by 22 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 19382.09090909
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 19382.09090909, with a leftover of 2e-09.
