824404 divided by 40 
The aim is to understand the frequency of 40 in 824404.

Let's proceed to step 1:
When dividing 8 by 40, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 40

Going ahead to step 2:
If we divide 82 by 40, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 80 from 82 to get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 40

Let's proceed to step 3:
24 divided by 40 is 0 with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 24, we end up with 24.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 40

Advancing to step 4:
40 goes into 244 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 206.0
Subtracting 240 from 244 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 40

Advancing to step 5:
40 goes into 40 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 2061.0
If we take 40 away from 40, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 40

On to step 6:
If we divide 4 by 40, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 20610.0
If we take 0 away from 4, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 can be fit into 40 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 20610.1
If we take 40 away from 40, 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.

Step 8:
0 divided by 40 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20610.1
Deduct 0 from 0 and we're left 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.

Moving on to step 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20610.1
Deduct 0 from 0 and we're left 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.

After the division, we end up with 20610.1 and a remainder of 0.0.
