173815 divided by 63 
The aim is to understand the frequency of 63 in 173815.

Let's proceed to step 1:
63 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 63

Step 2:
If we divide 17 by 63, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 63

Moving on to step 3:
173 divided by 63 is 2 with a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 126 from 173, we get 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 63

On to step 4:
478 divided by 63 is 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 441 from 478 and we're left with 37.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 63

Step 5:
The number 63 fits into 371 5 times, leaving a remainder of 56.
Use 5 as the next digit of our solution. 
Result so far: 275.0
Subtract 315 from 371 to get 56.
Bring next digit (5) of the dividend behind the 56 and repeat the process: 565 / 63

Advancing to step 6:
63 can be fit into 565 8 times, resulting in a remainder of 61.
The number 8 becomes the next digit in our result. 
Result so far: 2758.0
If we take 504 away from 565, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 7:
When dividing 610 by 63, we get 9 with a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 2758.9
If we subtract 567 from 610, we 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 8:
430 divided by 63 is 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 2758.96
If we take 378 away from 430, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
520 divided by 63 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 2758.968
Subtracting 504 from 520 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
When dividing 160 by 63, we get 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 2758.9682
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
63 goes into 340 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 2758.96825
Subtracting 315 from 340 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
When dividing 250 by 63, we get 3 with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 2758.968253
Deduct 189 from 250 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 13:
If we divide 610 by 63, we get 9 and a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 2758.9682539
Deduct 567 from 610 and we're left with 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 14:
The number 63 fits into 430 6 times, leaving a remainder of 52.
The next digit of our result is 6. 
Result so far: 2758.96825396
Deduct 378 from 430 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 2758.96825396 and a remainder of 5.2e-08.
