We look at the division of 80115858 by 63 
The aim is to understand the frequency of 63 in 80115858.

Step 1:
If we divide 8 by 63, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 63

Let's proceed to step 2:
80 divided by 63 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 63 from 80 leaves us with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 63

Advancing to step 3:
63 can be fit into 171 2 times, resulting in a remainder of 45.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 126 from 171, we get 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 63

Let's proceed to step 4:
63 goes into 451 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
If we subtract 441 from 451, we get 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 63

Going ahead to step 5:
63 goes into 105 1 times with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 1271.0
Deduct 63 from 105 and we're left with 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 63

Advancing to step 6:
When dividing 428 by 63, we get 6 with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 12716.0
Deduct 378 from 428 and we're left with 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 63

Going ahead to step 7:
63 can be fit into 505 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 127168.0
Subtracting 504 from 505 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 63

Going ahead to step 8:
If we divide 18 by 63, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 1271680.0
If we subtract 0 from 18, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
If we divide 180 by 63, we get 2 and a remainder of 54.
The next digit of our result is 2. 
Result so far: 1271680.2
Deduct 126 from 180 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
63 can be fit into 540 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 1271680.28
The remainder is 36 after subtracting 504 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
The number 63 fits into 360 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1271680.285
The remainder is 45 after subtracting 315 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 12:
If we divide 450 by 63, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 1271680.2857
If we subtract 441 from 450, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
The number 63 fits into 90 1 times, leaving a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1271680.28571
Subtracting 63 from 90 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 14:
When dividing 270 by 63, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 1271680.285714
The remainder is 18 after subtracting 252 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 15:
63 can be fit into 180 2 times, resulting in a remainder of 54.
The next digit of our result is 2. 
Result so far: 1271680.2857142
Subtract 126 from 180 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 16:
63 goes into 540 8 times with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 1271680.28571428
The remainder is 36 after subtracting 504 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 1271680.28571428 with a remainder of 3.6e-08.
