We divide 256423 by 22
The aim is to understand the frequency of 22 in 256423.

Step 1:
When dividing 2 by 22, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 22

Let's proceed to step 2:
The number 22 fits into 25 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 22 from 25, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 22

On to step 3:
When dividing 36 by 22, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 22 from 36, we get 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 22

Let's proceed to step 4:
144 divided by 22 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Subtract 132 from 144 to get 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 22

Advancing to step 5:
22 can be fit into 122 5 times, resulting in a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 1165.0
If we subtract 110 from 122, we get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 22

On to step 6:
123 divided by 22 is 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 11655.0
Deduct 110 from 123 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
When dividing 130 by 22, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 11655.5
Subtract 110 from 130 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.

Moving on to step 8:
200 divided by 22 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 11655.59
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.

Going ahead to step 9:
22 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11655.59
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.

Advancing to step 10:
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: 11655.5909
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.

Moving on to step 11:
The number 22 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 11655.5909
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.

Let's proceed to step 12:
The number 22 fits into 200 9 times, leaving a remainder of 2.
The next digit of our result is 9. 
Result so far: 11655.590909
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.

Moving on to step 13:
22 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 11655.590909
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.

On to step 14:
If we divide 200 by 22, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 11655.59090909
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.

Our division results in 11655.59090909 with a remaining 2e-09.
