80667796 divided by 825 
The aim is to understand the frequency of 825 in 80667796.

Let's proceed to step 1:
825 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 825

On to step 2:
The number 825 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 825

On to step 3:
825 can be fit into 806 0 times, resulting in a remainder of 806.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 806, we end up with 806.
Take the next digit (6) from the dividend and append it to 806, then repeat: 8066 / 825

Step 4:
825 goes into 8066 9 times with a remainder of 641.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 7425 from 8066, we get 641.
Take the next digit (7) from the dividend and append it to 641, then repeat: 6417 / 825

Advancing to step 5:
When dividing 6417 by 825, we get 7 with a remainder of 642.
The next digit of our result is 7. 
Result so far: 97.0
If we subtract 5775 from 6417, we get 642.
Fetch the next digit (7) from the dividend, attach it to 642 and continue: 6427 / 825

Moving on to step 6:
825 goes into 6427 7 times with a remainder of 652.
Put 7 as the next digit of the answer. 
Result so far: 977.0
The remainder is 652 after subtracting 5775 from 6427.
Include the next digit (9) from the dividend after 652, then repeat: 6529 / 825

Step 7:
825 can be fit into 6529 7 times, resulting in a remainder of 754.
Record the quotient 7 as the next digit in the result. 
Result so far: 9777.0
Deduct 5775 from 6529 and we're left with 754.
Bring next digit (6) of the dividend behind the 754 and repeat the process: 7546 / 825

On to step 8:
When dividing 7546 by 825, we get 9 with a remainder of 121.
Write down 9 as next digit of the result. 
Result so far: 97779.0
If we take 7425 away from 7546, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 9:
825 can be fit into 1210 1 times, resulting in a remainder of 385.
The number 1 becomes the next digit in our result. 
Result so far: 97779.1
Subtract 825 from 1210 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 10:
825 goes into 3850 4 times with a remainder of 550.
The number 4 becomes the next digit in our result. 
Result so far: 97779.14
The remainder is 550 after subtracting 3300 from 3850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 11:
If we divide 5500 by 825, we get 6 and a remainder of 550.
The next digit of our result is 6. 
Result so far: 97779.146
If we subtract 4950 from 5500, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 12:
825 goes into 5500 6 times with a remainder of 550.
Record the quotient 6 as the next digit in the result. 
Result so far: 97779.1466
Deduct 4950 from 5500 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Our division results in 97779.1466 with a remaining 0.0055.
