We look at the division of 30663865 by 800 
The aim is to understand the frequency of 800 in 30663865.

Moving on to step 1:
800 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 800

Going ahead to step 2:
If we divide 30 by 800, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 800

Advancing to step 3:
800 goes into 306 0 times with a remainder of 306.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 306 after subtracting 0 from 306.
Fetch the next digit (6) from the dividend, attach it to 306 and continue: 3066 / 800

Step 4:
If we divide 3066 by 800, we get 3 and a remainder of 666.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 2400 away from 3066, we end up with 666.
Grab the next digit (3) from the dividend, add it to 666, then carry on: 6663 / 800

Advancing to step 5:
When dividing 6663 by 800, we get 8 with a remainder of 263.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtracting 6400 from 6663 leaves us with 263.
Append the next digit (8) from the dividend to 263 and continue with: 2638 / 800

Going ahead to step 6:
If we divide 2638 by 800, we get 3 and a remainder of 238.
Record the quotient 3 as the next digit in the result. 
Result so far: 383.0
Subtracting 2400 from 2638 leaves us with 238.
Fetch the next digit (6) from the dividend, attach it to 238 and continue: 2386 / 800

On to step 7:
800 goes into 2386 2 times with a remainder of 786.
The next digit of our result is 2. 
Result so far: 3832.0
The remainder is 786 after subtracting 1600 from 2386.
Include the next digit (5) from the dividend after 786, then repeat: 7865 / 800

Moving on to step 8:
800 can be fit into 7865 9 times, resulting in a remainder of 665.
Record the quotient 9 as the next digit in the result. 
Result so far: 38329.0
Subtract 7200 from 7865 to get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Let's proceed to step 9:
800 can be fit into 6650 8 times, resulting in a remainder of 250.
Use 8 as the next digit of our solution. 
Result so far: 38329.8
Subtract 6400 from 6650 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
The number 800 fits into 2500 3 times, leaving a remainder of 100.
Write down 3 as next digit of the result. 
Result so far: 38329.83
Subtract 2400 from 2500 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
When dividing 1000 by 800, we get 1 with a remainder of 200.
Record the quotient 1 as the next digit in the result. 
Result so far: 38329.831
If we take 800 away from 1000, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
The number 800 fits into 2000 2 times, leaving a remainder of 400.
Put 2 as the next digit of the answer. 
Result so far: 38329.8312
The remainder is 400 after subtracting 1600 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 13:
800 goes into 4000 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 38329.83125
Deduct 4000 from 4000 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 14:
0 divided by 800 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 38329.83125
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.

Let's proceed to step 15:
0 divided by 800 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 38329.83125
If we take 0 away from 0, 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.

Our division results in 38329.83125 with a remaining 0.0.
