We're dividing 202409 by 40 
The aim is to understand the frequency of 40 in 202409.

Advancing to step 1:
When dividing 2 by 40, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 40

Advancing to step 2:
20 divided by 40 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 40

On to step 3:
202 divided by 40 is 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 200 from 202 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 40

On to step 4:
If we divide 24 by 40, we get 0 and a remainder of 24.
The next digit of our result is 0. 
Result so far: 50.0
If we take 0 away from 24, we end up with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 40

Let's proceed to step 5:
240 divided by 40 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 506.0
If we subtract 240 from 240, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 40

Let's proceed to step 6:
40 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 5060.0
If we subtract 0 from 9, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 40 fits into 90 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 5060.2
If we subtract 80 from 90, we 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:
40 goes into 100 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 5060.22
Subtracting 80 from 100 leaves us 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.

Our division results in 5060.22 with a remaining 0.02.
