Let's divide 808493 by 40
The aim is to understand the frequency of 40 in 808493.

Going ahead to step 1:
If we divide 8 by 40, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 40

Moving on to step 2:
40 can be fit into 80 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 80 from 80, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 40

Moving on to step 3:
8 divided by 40 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 40

Step 4:
40 can be fit into 84 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 202.0
If we subtract 80 from 84, we get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 40

Going ahead to step 5:
40 can be fit into 49 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 2021.0
If we subtract 40 from 49, we get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 40

Let's proceed to step 6:
When dividing 93 by 40, we get 2 with a remainder of 13.
The next digit of our result is 2. 
Result so far: 20212.0
If we subtract 80 from 93, we get 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:
130 divided by 40 is 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 20212.3
Subtracting 120 from 130 leaves us 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 8:
If we divide 100 by 40, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 20212.32
The remainder is 20 after subtracting 80 from 100.
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 9:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 20212.325
If we subtract 200 from 200, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20212.325
Subtracting 0 from 0 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.

Step 11:
When dividing 0 by 40, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20212.325
Subtract 0 from 0 to get 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 final result is 20212.325 with a remainder of 0.0.
