We're dividing 20438 by 22 
The aim is to understand the frequency of 22 in 20438.

On to 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
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 22

Going ahead to step 2:
22 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 22

Advancing to step 3:
If we divide 204 by 22, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 198 from 204 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 22

Advancing to step 4:
22 can be fit into 63 2 times, resulting in a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
The remainder is 19 after subtracting 44 from 63.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 22

Let's proceed to step 5:
The number 22 fits into 198 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 929.0
Subtracting 198 from 198 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 6:
22 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 929.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
If we divide 0 by 22, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 929.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 929.0, and the remainder is 0.0.
