Let's divide 67403960 by 800
The aim is to understand the frequency of 800 in 67403960.

Advancing to step 1:
If we divide 6 by 800, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 800

On to step 2:
The number 800 fits into 67 0 times, leaving a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Take the next digit (4) from the dividend and append it to 67, then repeat: 674 / 800

Going ahead to step 3:
When dividing 674 by 800, we get 0 with a remainder of 674.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 674, we get 674.
Take the next digit (0) from the dividend and append it to 674, then repeat: 6740 / 800

Moving on to step 4:
The number 800 fits into 6740 8 times, leaving a remainder of 340.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 6400 from 6740 leaves us with 340.
Grab the next digit (3) from the dividend, add it to 340, then carry on: 3403 / 800

Advancing to step 5:
The number 800 fits into 3403 4 times, leaving a remainder of 203.
The next digit of our result is 4. 
Result so far: 84.0
If we subtract 3200 from 3403, we get 203.
Take the next digit (9) from the dividend and append it to 203, then repeat: 2039 / 800

Let's proceed to step 6:
800 can be fit into 2039 2 times, resulting in a remainder of 439.
Write down 2 as next digit of the result. 
Result so far: 842.0
Deduct 1600 from 2039 and we're left with 439.
Grab the next digit (6) from the dividend, add it to 439, then carry on: 4396 / 800

Advancing to step 7:
800 goes into 4396 5 times with a remainder of 396.
Put 5 as the next digit of the answer. 
Result so far: 8425.0
If we take 4000 away from 4396, we end up with 396.
Include the next digit (0) from the dividend after 396, then repeat: 3960 / 800

On to step 8:
3960 divided by 800 is 4 with a remainder of 760.
Write down 4 as next digit of the result. 
Result so far: 84254.0
Subtract 3200 from 3960 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 9:
If we divide 7600 by 800, we get 9 and a remainder of 400.
Record the quotient 9 as the next digit in the result. 
Result so far: 84254.9
The remainder is 400 after subtracting 7200 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 10:
800 goes into 4000 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 84254.95
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.

Advancing to step 11:
The number 800 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 84254.95
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.

Going ahead to step 12:
0 divided by 800 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 84254.95
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.

The final result is 84254.95 with a remainder of 0.0.
