We look at the division of 965166 by 63 
The aim is to understand the frequency of 63 in 965166.

Advancing to step 1:
The number 63 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 63

Going ahead to step 2:
63 goes into 96 1 times with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 63 from 96 leaves us with 33.
Bring next digit (5) of the dividend behind the 33 and repeat the process: 335 / 63

Step 3:
63 can be fit into 335 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 315 from 335 leaves us with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 63

Step 4:
63 can be fit into 201 3 times, resulting in a remainder of 12.
The next digit of our result is 3. 
Result so far: 153.0
Subtracting 189 from 201 leaves us with 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 63

Let's proceed to step 5:
When dividing 126 by 63, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 1532.0
The remainder is 0 after subtracting 126 from 126.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 63

On to step 6:
6 divided by 63 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 15320.0
If we subtract 0 from 6, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
63 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 15320.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
63 goes into 600 9 times with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 15320.09
If we subtract 567 from 600, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
63 can be fit into 330 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15320.095
Subtracting 315 from 330 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
When dividing 150 by 63, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 15320.0952
Subtract 126 from 150 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
When dividing 240 by 63, we get 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 15320.09523
If we take 189 away from 240, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 12:
When dividing 510 by 63, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 15320.095238
If we subtract 504 from 510, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
When dividing 60 by 63, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 15320.095238
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
The number 63 fits into 600 9 times, leaving a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 15320.09523809
Subtracting 567 from 600 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The quotient of the division is 15320.09523809, and the remainder is 3.3e-08.
