We're dividing 390693 by 40 
The aim is to understand the frequency of 40 in 390693.

Going ahead to step 1:
When dividing 3 by 40, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 40

Moving on to step 2:
40 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 40

On to step 3:
If we divide 390 by 40, we get 9 and a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 360 from 390 leaves us with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 40

Let's proceed to step 4:
40 goes into 306 7 times with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Deduct 280 from 306 and we're left with 26.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 40

Going ahead to step 5:
269 divided by 40 is 6 with a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 976.0
If we subtract 240 from 269, we get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 40

Advancing to step 6:
When dividing 293 by 40, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 9767.0
If we subtract 280 from 293, 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.

Advancing to step 7:
40 goes into 130 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 9767.3
Subtract 120 from 130 to 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.

Moving on to step 8:
40 can be fit into 100 2 times, resulting in a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 9767.32
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.

Advancing to step 9:
200 divided by 40 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 9767.325
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.

Step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9767.325
If we subtract 0 from 0, 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.

Step 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9767.325
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.

In conclusion, the division gives 9767.325 with a balance of 0.0.
