We divide 427572 by 22
The aim is to understand the frequency of 22 in 427572.

Step 1:
If we divide 4 by 22, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 22

Going ahead to step 2:
22 can be fit into 42 1 times, resulting in a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 22 from 42 leaves us with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 22

Moving on to step 3:
22 can be fit into 207 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 198 from 207 and we're left with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 22

Advancing to step 4:
22 can be fit into 95 4 times, resulting in a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 194.0
Subtracting 88 from 95 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 22

Advancing to step 5:
The number 22 fits into 77 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 1943.0
If we take 66 away from 77, we end up with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 22

Moving on to step 6:
22 can be fit into 112 5 times, resulting in a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 19435.0
Subtracting 110 from 112 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.

Let's proceed to step 7:
When dividing 20 by 22, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 19435.0
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.

Going ahead to step 8:
200 divided by 22 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 19435.09
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.

Advancing 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: 19435.09
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:
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: 19435.0909
Deduct 198 from 200 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 11:
22 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 19435.0909
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.

Advancing to step 12:
22 goes into 200 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 19435.090909
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.

Step 13:
22 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 19435.090909
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.

Going ahead to step 14:
22 can be fit into 200 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 19435.09090909
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.

Our division results in 19435.09090909 with a remaining 2e-09.
