We look at the division of 448472 by 22 
The aim is to understand the frequency of 22 in 448472.

Moving on to step 1:
When dividing 4 by 22, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 22

Going ahead to step 2:
When dividing 44 by 22, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 0 after subtracting 44 from 44.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 22

Advancing to step 3:
22 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 8 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 22

Advancing to step 4:
The number 22 fits into 84 3 times, leaving a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 203.0
If we subtract 66 from 84, we get 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 22

Let's proceed to step 5:
187 divided by 22 is 8 with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 2038.0
Deduct 176 from 187 and we're left with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 22

Advancing to step 6:
When dividing 112 by 22, we get 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 20385.0
Deduct 110 from 112 and we're left 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.

Step 7:
22 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 20385.0
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:
If we divide 200 by 22, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 20385.09
The remainder is 2 after subtracting 198 from 200.
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 9:
22 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 20385.09
If we take 0 away from 20, we end up 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.

Step 10:
22 can be fit into 200 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 20385.0909
Subtracting 198 from 200 leaves us 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.

Moving on to step 11:
20 divided by 22 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 20385.0909
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.

Let's proceed to step 12:
22 can be fit into 200 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 20385.090909
If we subtract 198 from 200, 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.

Let's proceed to step 13:
22 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 20385.090909
Subtract 0 from 20 to 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.

On to step 14:
22 goes into 200 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 20385.09090909
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.

After the division, we end up with 20385.09090909 and a remainder of 2e-09.
