We look at the division of 578222 by 40 
The aim is to understand the frequency of 40 in 578222.

Advancing to step 1:
When dividing 5 by 40, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 40

Moving on to step 2:
57 divided by 40 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 40 from 57 to get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 40

Moving on to step 3:
When dividing 178 by 40, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 160 from 178, we get 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 40

Advancing to step 4:
40 goes into 182 4 times with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 144.0
If we subtract 160 from 182, we get 22.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 40

Going ahead to step 5:
When dividing 222 by 40, we get 5 with a remainder of 22.
The next digit of our result is 5. 
Result so far: 1445.0
If we subtract 200 from 222, we get 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 40

Advancing to step 6:
40 can be fit into 222 5 times, resulting in a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 14455.0
If we take 200 away from 222, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
40 goes into 220 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 14455.5
Deduct 200 from 220 and we're left 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.

Going ahead to step 8:
If we divide 200 by 40, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 14455.55
Subtracting 200 from 200 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.

The final outcome is 14455.55, with a leftover of 0.0.
