We look at the division of 76959574 by 963 
The aim is to understand the frequency of 963 in 76959574.

Advancing to step 1:
When dividing 7 by 963, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 963

Going ahead to step 2:
When dividing 76 by 963, we get 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Include the next digit (9) from the dividend after 76, then repeat: 769 / 963

On to step 3:
963 can be fit into 769 0 times, resulting in a remainder of 769.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 769, we get 769.
Bring next digit (5) of the dividend behind the 769 and repeat the process: 7695 / 963

Going ahead to step 4:
963 goes into 7695 7 times with a remainder of 954.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 6741 from 7695 to get 954.
Include the next digit (9) from the dividend after 954, then repeat: 9549 / 963

Advancing to step 5:
If we divide 9549 by 963, we get 9 and a remainder of 882.
Use 9 as the next digit of our solution. 
Result so far: 79.0
If we subtract 8667 from 9549, we get 882.
Append the next digit (5) from the dividend to 882 and continue with: 8825 / 963

Step 6:
963 goes into 8825 9 times with a remainder of 158.
Put 9 as the next digit of the answer. 
Result so far: 799.0
If we subtract 8667 from 8825, we get 158.
Grab the next digit (7) from the dividend, add it to 158, then carry on: 1587 / 963

Going ahead to step 7:
963 goes into 1587 1 times with a remainder of 624.
The number 1 becomes the next digit in our result. 
Result so far: 7991.0
If we take 963 away from 1587, we end up with 624.
Fetch the next digit (4) from the dividend, attach it to 624 and continue: 6244 / 963

Advancing to step 8:
If we divide 6244 by 963, we get 6 and a remainder of 466.
The next digit of our result is 6. 
Result so far: 79916.0
Deduct 5778 from 6244 and we're left with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 9:
4660 divided by 963 is 4 with a remainder of 808.
Use 4 as the next digit of our solution. 
Result so far: 79916.4
Deduct 3852 from 4660 and we're left with 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Step 10:
963 can be fit into 8080 8 times, resulting in a remainder of 376.
Write down 8 as next digit of the result. 
Result so far: 79916.48
The remainder is 376 after subtracting 7704 from 8080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 11:
3760 divided by 963 is 3 with a remainder of 871.
Use 3 as the next digit of our solution. 
Result so far: 79916.483
Deduct 2889 from 3760 and we're left with 871.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8710, and continue the process.

On to step 12:
963 goes into 8710 9 times with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 79916.4839
Subtract 8667 from 8710 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 13:
The number 963 fits into 430 0 times, leaving a remainder of 430.
The next digit of our result is 0. 
Result so far: 79916.4839
If we take 0 away from 430, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 14:
When dividing 4300 by 963, we get 4 with a remainder of 448.
Use 4 as the next digit of our solution. 
Result so far: 79916.483904
The remainder is 448 after subtracting 3852 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 15:
4480 divided by 963 is 4 with a remainder of 628.
The next digit of our result is 4. 
Result so far: 79916.4839044
If we subtract 3852 from 4480, we get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

After the division, we end up with 79916.4839044 and a remainder of 6.28e-06.
