We look at the division of 17187 by 63 
The aim is to understand the frequency of 63 in 17187.

Step 1:
The number 63 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 63

Moving on to step 2:
17 divided by 63 is 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 63

Step 3:
When dividing 171 by 63, we get 2 with a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 126 from 171 leaves us with 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 63

Moving on to step 4:
63 goes into 458 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 27.0
The remainder is 17 after subtracting 441 from 458.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 63

Let's proceed to step 5:
63 goes into 177 2 times with a remainder of 51.
Record the quotient 2 as the next digit in the result. 
Result so far: 272.0
Subtracting 126 from 177 leaves us 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.

On to step 6:
The number 63 fits into 510 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 272.8
Deduct 504 from 510 and we're left with 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:
The number 63 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 272.8
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.

Going ahead to step 8:
63 can be fit into 600 9 times, resulting in a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 272.809
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.

Advancing to step 9:
The number 63 fits into 330 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 272.8095
If we take 315 away from 330, we end up 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.

Step 10:
63 can be fit into 150 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 272.80952
If we take 126 away from 150, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
240 divided by 63 is 3 with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 272.809523
Subtract 189 from 240 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 12:
The number 63 fits into 510 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 272.8095238
Subtracting 504 from 510 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
The number 63 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 272.8095238
If we subtract 0 from 60, we 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.

In conclusion, the division gives 272.8095238 with a balance of 6e-08.
