We're dividing 405437 by 22 
The aim is to understand the frequency of 22 in 405437.

Step 1:
The number 22 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 22

Advancing to step 2:
22 goes into 40 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 22 from 40 leaves us with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 22

Going ahead to step 3:
The number 22 fits into 185 8 times, leaving a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 176 from 185 leaves us with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 22

Going ahead to step 4:
94 divided by 22 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 184.0
The remainder is 6 after subtracting 88 from 94.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 22

Advancing to step 5:
The number 22 fits into 63 2 times, leaving a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 1842.0
The remainder is 19 after subtracting 44 from 63.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 22

Going ahead to step 6:
22 goes into 197 8 times with a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 18428.0
The remainder is 21 after subtracting 176 from 197.
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 22 fits into 210 9 times, leaving a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 18428.9
The remainder is 12 after subtracting 198 from 210.
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 8:
The number 22 fits into 120 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 18428.95
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.

Going ahead to step 9:
If we divide 100 by 22, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 18428.954
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.

Step 10:
22 goes into 120 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 18428.9545
Subtracting 110 from 120 leaves us 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 11:
If we divide 100 by 22, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 18428.95454
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.

On to step 12:
22 goes into 120 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 18428.954545
Subtract 110 from 120 to 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.

Moving on to step 13:
100 divided by 22 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 18428.9545454
The remainder is 12 after subtracting 88 from 100.
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 14:
When dividing 120 by 22, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 18428.95454545
If we take 110 away from 120, we end up 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.

In conclusion, the division gives 18428.95454545 with a balance of 1e-08.
