We divide 771488 by 9
The aim is to understand the frequency of 9 in 771488.

Let's proceed to step 1:
If we divide 7 by 9, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 9

Moving on to step 2:
When dividing 77 by 9, we get 8 with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 72 from 77, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 9

Step 3:
9 goes into 51 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 85.0
If we subtract 45 from 51, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 9

Step 4:
9 can be fit into 64 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 857.0
If we subtract 63 from 64, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 9

Let's proceed to step 5:
9 can be fit into 18 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 8572.0
The remainder is 0 after subtracting 18 from 18.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 9

Advancing to step 6:
If we divide 8 by 9, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 85720.0
If we take 0 away from 8, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
The number 9 fits into 80 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 85720.8
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
9 goes into 80 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 85720.88
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 85720.88, with a leftover of 0.008.
