We're dividing 9900363 by 689 
The aim is to understand the frequency of 689 in 9900363.

Going ahead to step 1:
9 divided by 689 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 689

Moving on to step 2:
99 divided by 689 is 0 with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Include the next digit (0) from the dividend after 99, then repeat: 990 / 689

Moving on to step 3:
689 can be fit into 990 1 times, resulting in a remainder of 301.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 689 away from 990, we end up with 301.
Bring next digit (0) of the dividend behind the 301 and repeat the process: 3010 / 689

Moving on to step 4:
The number 689 fits into 3010 4 times, leaving a remainder of 254.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 2756 away from 3010, we end up with 254.
Fetch the next digit (3) from the dividend, attach it to 254 and continue: 2543 / 689

On to step 5:
If we divide 2543 by 689, we get 3 and a remainder of 476.
Use 3 as the next digit of our solution. 
Result so far: 143.0
If we subtract 2067 from 2543, we get 476.
Append the next digit (6) from the dividend to 476 and continue with: 4766 / 689

Going ahead to step 6:
4766 divided by 689 is 6 with a remainder of 632.
Use 6 as the next digit of our solution. 
Result so far: 1436.0
The remainder is 632 after subtracting 4134 from 4766.
Fetch the next digit (3) from the dividend, attach it to 632 and continue: 6323 / 689

Moving on to step 7:
689 can be fit into 6323 9 times, resulting in a remainder of 122.
Put 9 as the next digit of the answer. 
Result so far: 14369.0
If we take 6201 away from 6323, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 8:
The number 689 fits into 1220 1 times, leaving a remainder of 531.
Write down 1 as next digit of the result. 
Result so far: 14369.1
If we take 689 away from 1220, we end up with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Let's proceed to step 9:
The number 689 fits into 5310 7 times, leaving a remainder of 487.
The number 7 becomes the next digit in our result. 
Result so far: 14369.17
If we subtract 4823 from 5310, we get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

On to step 10:
4870 divided by 689 is 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 14369.177
Subtract 4823 from 4870 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Our division results in 14369.177 with a remaining 0.0047.
