906019 divided by 9 
The aim is to understand the frequency of 9 in 906019.

Let's proceed to step 1:
If we divide 9 by 9, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 9 from 9, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 9

Step 2:
9 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 9

Advancing to step 3:
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: 100.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 9

Let's proceed to step 4:
When dividing 60 by 9, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 1006.0
Subtracting 54 from 60 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 9

On to step 5:
9 can be fit into 61 6 times, resulting in a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 10066.0
Deduct 54 from 61 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 9

Let's proceed to step 6:
9 goes into 79 8 times with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 100668.0
If we take 72 away from 79, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
9 can be fit into 70 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 100668.7
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
When dividing 70 by 9, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 100668.77
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 100668.77 and a remainder of 0.007.
