We look at the division of 550478 by 22 
The aim is to understand the frequency of 22 in 550478.

Moving on to step 1:
If we divide 5 by 22, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 22

Advancing to step 2:
When dividing 55 by 22, we get 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 11 after subtracting 44 from 55.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 22

Moving on to step 3:
The number 22 fits into 110 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 0 after subtracting 110 from 110.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 22

Going ahead to step 4:
When dividing 4 by 22, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 250.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 22

Going ahead to step 5:
22 can be fit into 47 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2502.0
The remainder is 3 after subtracting 44 from 47.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 22

On to step 6:
22 can be fit into 38 1 times, resulting in a remainder of 16.
The next digit of our result is 1. 
Result so far: 25021.0
If we subtract 22 from 38, we get 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 7:
22 goes into 160 7 times with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 25021.7
If we take 154 away from 160, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
When dividing 60 by 22, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 25021.72
Deduct 44 from 60 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.

Step 9:
160 divided by 22 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 25021.727
Subtract 154 from 160 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
60 divided by 22 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 25021.7272
If we take 44 away from 60, we end up 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.

Advancing to step 11:
22 can be fit into 160 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 25021.72727
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.

Moving on to step 12:
The number 22 fits into 60 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 25021.727272
If we subtract 44 from 60, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
22 can be fit into 160 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 25021.7272727
Subtract 154 from 160 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
22 can be fit into 60 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 25021.72727272
If we take 44 away from 60, we end up 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.

Our division results in 25021.72727272 with a remaining 1.6e-08.
