We divide 726141 by 9
The aim is to understand the frequency of 9 in 726141.

Let's proceed to step 1:
The number 9 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 9

Going ahead to step 2:
72 divided by 9 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 72 from 72 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 9

Advancing to step 3:
9 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 80.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 9

Moving on to step 4:
The number 9 fits into 61 6 times, leaving a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 806.0
If we subtract 54 from 61, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 9

On to step 5:
74 divided by 9 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 8068.0
Subtracting 72 from 74 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 9

Advancing to step 6:
9 goes into 21 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 80682.0
Deduct 18 from 21 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
30 divided by 9 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 80682.3
Subtract 27 from 30 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
9 can be fit into 30 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 80682.33
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 80682.33 with a remainder of 0.003.
