89680387 ÷ 963 
The aim is to understand the frequency of 963 in 89680387.

Going ahead to step 1:
The number 963 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 963

Moving on to step 2:
963 goes into 89 0 times with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Bring next digit (6) of the dividend behind the 89 and repeat the process: 896 / 963

Moving on to step 3:
963 goes into 896 0 times with a remainder of 896.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 896 leaves us with 896.
Take the next digit (8) from the dividend and append it to 896, then repeat: 8968 / 963

On to step 4:
8968 divided by 963 is 9 with a remainder of 301.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 8667 from 8968 and we're left with 301.
Bring next digit (0) of the dividend behind the 301 and repeat the process: 3010 / 963

Let's proceed to step 5:
3010 divided by 963 is 3 with a remainder of 121.
Write down 3 as next digit of the result. 
Result so far: 93.0
Deduct 2889 from 3010 and we're left with 121.
Grab the next digit (3) from the dividend, add it to 121, then carry on: 1213 / 963

Step 6:
963 can be fit into 1213 1 times, resulting in a remainder of 250.
The next digit of our result is 1. 
Result so far: 931.0
Subtract 963 from 1213 to get 250.
Take the next digit (8) from the dividend and append it to 250, then repeat: 2508 / 963

Let's proceed to step 7:
The number 963 fits into 2508 2 times, leaving a remainder of 582.
Use 2 as the next digit of our solution. 
Result so far: 9312.0
Subtract 1926 from 2508 to get 582.
Append the next digit (7) from the dividend to 582 and continue with: 5827 / 963

Going ahead to step 8:
When dividing 5827 by 963, we get 6 with a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 93126.0
Deduct 5778 from 5827 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
490 divided by 963 is 0 with a remainder of 490.
Write down 0 as next digit of the result. 
Result so far: 93126.0
Subtracting 0 from 490 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 10:
963 can be fit into 4900 5 times, resulting in a remainder of 85.
The next digit of our result is 5. 
Result so far: 93126.05
If we subtract 4815 from 4900, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 11:
850 divided by 963 is 0 with a remainder of 850.
The next digit of our result is 0. 
Result so far: 93126.05
The remainder is 850 after subtracting 0 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Let's proceed to step 12:
963 can be fit into 8500 8 times, resulting in a remainder of 796.
Put 8 as the next digit of the answer. 
Result so far: 93126.0508
If we subtract 7704 from 8500, we get 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Step 13:
963 can be fit into 7960 8 times, resulting in a remainder of 256.
The number 8 becomes the next digit in our result. 
Result so far: 93126.05088
If we subtract 7704 from 7960, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final result is 93126.05088 with a remainder of 0.000256.
