We're dividing 17310311 by 963 
The aim is to understand the frequency of 963 in 17310311.

Moving on to step 1:
963 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 963

Moving on to step 2:
963 can be fit into 17 0 times, resulting in a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 963

Going ahead to step 3:
963 can be fit into 173 0 times, resulting in a remainder of 173.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 173, we get 173.
Append the next digit (1) from the dividend to 173 and continue with: 1731 / 963

Moving on to step 4:
When dividing 1731 by 963, we get 1 with a remainder of 768.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 963 from 1731 to get 768.
Include the next digit (0) from the dividend after 768, then repeat: 7680 / 963

Advancing to step 5:
963 can be fit into 7680 7 times, resulting in a remainder of 939.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 939 after subtracting 6741 from 7680.
Take the next digit (3) from the dividend and append it to 939, then repeat: 9393 / 963

Let's proceed to step 6:
When dividing 9393 by 963, we get 9 with a remainder of 726.
Record the quotient 9 as the next digit in the result. 
Result so far: 179.0
The remainder is 726 after subtracting 8667 from 9393.
Include the next digit (1) from the dividend after 726, then repeat: 7261 / 963

Going ahead to step 7:
963 goes into 7261 7 times with a remainder of 520.
The next digit of our result is 7. 
Result so far: 1797.0
If we take 6741 away from 7261, we end up with 520.
Include the next digit (1) from the dividend after 520, then repeat: 5201 / 963

On to step 8:
963 goes into 5201 5 times with a remainder of 386.
The number 5 becomes the next digit in our result. 
Result so far: 17975.0
If we subtract 4815 from 5201, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 9:
The number 963 fits into 3860 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 17975.4
The remainder is 8 after subtracting 3852 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
80 divided by 963 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 17975.4
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
963 can be fit into 800 0 times, resulting in a remainder of 800.
Put 0 as the next digit of the answer. 
Result so far: 17975.4
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Our division results in 17975.4 with a remaining 0.08.
