We're dividing 644889 by 22 
The aim is to understand the frequency of 22 in 644889.

Advancing to step 1:
If we divide 6 by 22, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 22

Step 2:
64 divided by 22 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 44 from 64, we get 20.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 22

Advancing to step 3:
22 can be fit into 204 9 times, resulting in a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we take 198 away from 204, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 22

Advancing to step 4:
22 can be fit into 68 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 293.0
Deduct 66 from 68 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 22

Going ahead to step 5:
22 goes into 28 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 2931.0
Deduct 22 from 28 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 22

Advancing to step 6:
If we divide 69 by 22, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 29313.0
Deduct 66 from 69 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
If we divide 30 by 22, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 29313.1
If we take 22 away from 30, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
22 goes into 80 3 times with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 29313.13
The remainder is 14 after subtracting 66 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
22 can be fit into 140 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 29313.136
Subtracting 132 from 140 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
22 goes into 80 3 times with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 29313.1363
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
140 divided by 22 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 29313.13636
If we take 132 away from 140, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
80 divided by 22 is 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 29313.136363
The remainder is 14 after subtracting 66 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
If we divide 140 by 22, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 29313.1363636
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
80 divided by 22 is 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 29313.13636363
If we subtract 66 from 80, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 29313.13636363 and a remainder of 1.4e-08.
