616498 ÷ 9 
The aim is to understand the frequency of 9 in 616498.

Let's proceed to step 1:
If we divide 6 by 9, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 9

Let's proceed to step 2:
When dividing 61 by 9, we get 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 54 from 61 to get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 9

Let's proceed to step 3:
If we divide 76 by 9, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtract 72 from 76 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 9

Advancing to step 4:
44 divided by 9 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 684.0
Deduct 36 from 44 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 9

Going ahead to step 5:
The number 9 fits into 89 9 times, leaving a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 6849.0
Deduct 81 from 89 and we're left with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 9

Let's proceed to step 6:
The number 9 fits into 88 9 times, leaving a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 68499.0
Subtract 81 from 88 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
The number 9 fits into 70 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 68499.7
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
70 divided by 9 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 68499.77
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.

The quotient of the division is 68499.77, and the remainder is 0.007.
