We look at the division of 40306430 by 800 
The aim is to understand the frequency of 800 in 40306430.

Let's proceed to step 1:
When dividing 4 by 800, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 800

On to step 2:
40 divided by 800 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 800

Advancing to step 3:
When dividing 403 by 800, we get 0 with a remainder of 403.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 403 to get 403.
Append the next digit (0) from the dividend to 403 and continue with: 4030 / 800

Advancing to step 4:
When dividing 4030 by 800, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 4000 away from 4030, we end up with 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 800

Advancing to step 5:
800 goes into 306 0 times with a remainder of 306.
The next digit of our result is 0. 
Result so far: 50.0
If we subtract 0 from 306, we get 306.
Bring next digit (4) of the dividend behind the 306 and repeat the process: 3064 / 800

Moving on to step 6:
800 goes into 3064 3 times with a remainder of 664.
The number 3 becomes the next digit in our result. 
Result so far: 503.0
Subtract 2400 from 3064 to get 664.
Include the next digit (3) from the dividend after 664, then repeat: 6643 / 800

Advancing to step 7:
The number 800 fits into 6643 8 times, leaving a remainder of 243.
The number 8 becomes the next digit in our result. 
Result so far: 5038.0
Subtract 6400 from 6643 to get 243.
Bring next digit (0) of the dividend behind the 243 and repeat the process: 2430 / 800

Step 8:
800 can be fit into 2430 3 times, resulting in a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 50383.0
If we take 2400 away from 2430, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
The number 800 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 50383.0
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 10:
The number 800 fits into 3000 3 times, leaving a remainder of 600.
The next digit of our result is 3. 
Result so far: 50383.03
The remainder is 600 after subtracting 2400 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 11:
800 goes into 6000 7 times with a remainder of 400.
Write down 7 as next digit of the result. 
Result so far: 50383.037
If we take 5600 away from 6000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 12:
If we divide 4000 by 800, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 50383.0375
Subtract 4000 from 4000 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 13:
When dividing 0 by 800, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 50383.0375
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.

Going ahead to step 14:
If we divide 0 by 800, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 50383.0375
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 50383.0375 with a remainder of 0.0.
