616810 divided by 9 
The aim is to understand the frequency of 9 in 616810.

Moving on to step 1:
9 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 9

Let's proceed to step 2:
61 divided by 9 is 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 54 from 61 and we're left with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 9

Going ahead to step 3:
When dividing 76 by 9, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 68.0
Subtract 72 from 76 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 9

On to step 4:
When dividing 48 by 9, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 685.0
Subtract 45 from 48 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 9

Advancing to step 5:
9 goes into 31 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 6853.0
Subtracting 27 from 31 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 9

Let's proceed to step 6:
The number 9 fits into 40 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 68534.0
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
When dividing 40 by 9, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 68534.4
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 9 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 68534.44
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 68534.44 and a remainder of 0.004.
