We're dividing 801099 by 9 
The aim is to understand the frequency of 9 in 801099.

Advancing to step 1:
When dividing 8 by 9, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 9

Let's proceed to step 2:
If we divide 80 by 9, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 72 from 80 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 9

Going ahead to step 3:
When dividing 81 by 9, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 89.0
The remainder is 0 after subtracting 81 from 81.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 9

Let's proceed to step 4:
0 divided by 9 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 890.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 9

Going ahead to step 5:
When dividing 9 by 9, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 8901.0
Subtracting 9 from 9 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 9

Advancing to step 6:
9 goes into 9 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 89011.0
Subtracting 9 from 9 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
9 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 89011.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 9 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 89011.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 89011.0 with a remaining 0.0.
