We divide 40419784 by 5
The aim is to understand the frequency of 5 in 40419784.

On to step 1:
4 divided by 5 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 5

Going ahead to step 2:
5 goes into 40 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 0 after subtracting 40 from 40.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 5

Moving on to step 3:
When dividing 4 by 5, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 5

Advancing to step 4:
5 goes into 41 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 808.0
If we subtract 40 from 41, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 5

Advancing to step 5:
The number 5 fits into 19 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 8083.0
The remainder is 4 after subtracting 15 from 19.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 5

Advancing to step 6:
The number 5 fits into 47 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 80839.0
The remainder is 2 after subtracting 45 from 47.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 5

Let's proceed to step 7:
5 can be fit into 28 5 times, resulting in a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 808395.0
Deduct 25 from 28 and we're left with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 5

Advancing to step 8:
5 can be fit into 34 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 8083956.0
The remainder is 4 after subtracting 30 from 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
When dividing 40 by 5, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 8083956.8
Subtract 40 from 40 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.

Step 10:
0 divided by 5 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8083956.8
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.

Let's proceed to step 11:
If we divide 0 by 5, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8083956.8
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.

The final result is 8083956.8 with a remainder of 0.0.
