800738 divided by 9 
The aim is to understand the frequency of 9 in 800738.

Going ahead to step 1:
The number 9 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 9

Let's proceed to step 2:
When dividing 80 by 9, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 72 from 80 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 9

Advancing to step 3:
9 can be fit into 80 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 88.0
If we subtract 72 from 80, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 9

Moving on to step 4:
9 goes into 87 9 times with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 889.0
If we take 81 away from 87, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 9

Step 5:
The number 9 fits into 63 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 8897.0
If we subtract 63 from 63, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 9

Advancing to step 6:
8 divided by 9 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 88970.0
The remainder is 8 after subtracting 0 from 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:
80 divided by 9 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 88970.8
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
80 divided by 9 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 88970.88
Subtracting 72 from 80 leaves us 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.

After the division, we end up with 88970.88 and a remainder of 0.008.
