642868 divided by 22 
The aim is to understand the frequency of 22 in 642868.

Moving on to step 1:
6 divided by 22 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 22

Let's proceed to step 2:
22 can be fit into 64 2 times, resulting in a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 44 from 64, we get 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 22

Step 3:
202 divided by 22 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 29.0
If we subtract 198 from 202, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 22

Step 4:
48 divided by 22 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 292.0
Subtracting 44 from 48 leaves us with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 22

Advancing to step 5:
22 can be fit into 46 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2922.0
If we take 44 away from 46, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 22

Going ahead to step 6:
28 divided by 22 is 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 29221.0
Subtract 22 from 28 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.

On to step 7:
If we divide 60 by 22, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 29221.2
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 8:
160 divided by 22 is 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 29221.27
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.

On to step 9:
22 can be fit into 60 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 29221.272
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.

Going ahead to step 10:
160 divided by 22 is 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 29221.2727
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.

Moving on to step 11:
The number 22 fits into 60 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 29221.27272
Subtract 44 from 60 to 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.

Going ahead to step 12:
160 divided by 22 is 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 29221.272727
If we subtract 154 from 160, we 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.

Let's proceed to step 13:
22 goes into 60 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 29221.2727272
Subtracting 44 from 60 leaves us 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.

Moving on to step 14:
The number 22 fits into 160 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 29221.27272727
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.

The final result is 29221.27272727 with a remainder of 6e-09.
