680127 ÷ 9 
The aim is to understand the frequency of 9 in 680127.

On to step 1:
When dividing 6 by 9, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 9

Advancing to step 2:
9 can be fit into 68 7 times, resulting in a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 63 from 68 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 9

Going ahead to step 3:
The number 9 fits into 50 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 75.0
If we subtract 45 from 50, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 9

Step 4:
The number 9 fits into 51 5 times, leaving a remainder of 6.
The next digit of our result is 5. 
Result so far: 755.0
If we take 45 away from 51, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 9

Moving on to step 5:
If we divide 62 by 9, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 7556.0
If we subtract 54 from 62, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 9

On to step 6:
9 goes into 87 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 75569.0
If we take 81 away from 87, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 9 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 75569.6
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
9 can be fit into 60 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 75569.66
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 75569.66 and a remainder of 0.006.
