Let's divide 30046782 by 80
The aim is to understand the frequency of 80 in 30046782.

Step 1:
When dividing 3 by 80, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 80

Moving on to step 2:
80 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 80

Step 3:
80 can be fit into 300 3 times, resulting in a remainder of 60.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 240 from 300 to get 60.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 80

On to step 4:
604 divided by 80 is 7 with a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we subtract 560 from 604, we get 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 80

Going ahead to step 5:
446 divided by 80 is 5 with a remainder of 46.
The next digit of our result is 5. 
Result so far: 375.0
Subtract 400 from 446 to get 46.
Take the next digit (7) from the dividend and append it to 46, then repeat: 467 / 80

On to step 6:
467 divided by 80 is 5 with a remainder of 67.
Record the quotient 5 as the next digit in the result. 
Result so far: 3755.0
Subtract 400 from 467 to get 67.
Fetch the next digit (8) from the dividend, attach it to 67 and continue: 678 / 80

Advancing to step 7:
When dividing 678 by 80, we get 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 37558.0
Deduct 640 from 678 and we're left with 38.
Include the next digit (2) from the dividend after 38, then repeat: 382 / 80

Going ahead to step 8:
382 divided by 80 is 4 with a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 375584.0
Subtract 320 from 382 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
When dividing 620 by 80, we get 7 with a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 375584.7
Subtract 560 from 620 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
600 divided by 80 is 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 375584.77
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 375584.77 with a remaining 0.04.
