We look at the division of 388631 by 22 
The aim is to understand the frequency of 22 in 388631.

Advancing to step 1:
The number 22 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 22

Step 2:
38 divided by 22 is 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 16 after subtracting 22 from 38.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 22

Advancing to step 3:
22 goes into 168 7 times with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 154 away from 168, we end up with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 22

Advancing to step 4:
146 divided by 22 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 176.0
Subtract 132 from 146 to get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 22

Advancing to step 5:
The number 22 fits into 143 6 times, leaving a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 1766.0
Deduct 132 from 143 and we're left with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 22

Advancing to step 6:
22 can be fit into 111 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 17665.0
Subtracting 110 from 111 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
22 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 17665.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 22, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 17665.04
The remainder is 12 after subtracting 88 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
The number 22 fits into 120 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 17665.045
If we take 110 away from 120, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
If we divide 100 by 22, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 17665.0454
If we take 88 away from 100, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
120 divided by 22 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 17665.04545
Deduct 110 from 120 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
If we divide 100 by 22, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 17665.045454
Deduct 88 from 100 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
120 divided by 22 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 17665.0454545
Deduct 110 from 120 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
100 divided by 22 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 17665.04545454
The remainder is 12 after subtracting 88 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 17665.04545454 with a remaining 1.2e-08.
