We look at the division of 63615454 by 63 
The aim is to understand the frequency of 63 in 63615454.

Moving on to step 1:
6 divided by 63 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 63

Going ahead to step 2:
63 can be fit into 63 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 63 from 63, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 63

Going ahead to step 3:
6 divided by 63 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 6, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 63

Step 4:
The number 63 fits into 61 0 times, leaving a remainder of 61.
The next digit of our result is 0. 
Result so far: 100.0
If we take 0 away from 61, we end up with 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 63

On to step 5:
If we divide 615 by 63, we get 9 and a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 1009.0
If we take 567 away from 615, we end up with 48.
Append the next digit (4) from the dividend to 48 and continue with: 484 / 63

Step 6:
If we divide 484 by 63, we get 7 and a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 10097.0
Subtract 441 from 484 to get 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 63

Moving on to step 7:
435 divided by 63 is 6 with a remainder of 57.
Record the quotient 6 as the next digit in the result. 
Result so far: 100976.0
Subtracting 378 from 435 leaves us with 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 63

Let's proceed to step 8:
574 divided by 63 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 1009769.0
Subtract 567 from 574 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
63 can be fit into 70 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 1009769.1
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
63 goes into 70 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1009769.11
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 1009769.11 with a balance of 0.007.
