We divide 583043 by 9
The aim is to understand the frequency of 9 in 583043.

Step 1:
9 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 9

Let's proceed to step 2:
58 divided by 9 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 54 from 58 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 9

Advancing to step 3:
9 goes into 43 4 times with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we take 36 away from 43, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 9

On to step 4:
When dividing 70 by 9, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 647.0
If we subtract 63 from 70, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 9

Moving on to step 5:
The number 9 fits into 74 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 6478.0
Deduct 72 from 74 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 9

On to step 6:
9 goes into 23 2 times with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 64782.0
If we subtract 18 from 23, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
If we divide 50 by 9, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 64782.5
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
If we divide 50 by 9, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 64782.55
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 64782.55 with a remainder of 0.005.
