517830 ÷ 63 
The aim is to understand the frequency of 63 in 517830.

Going ahead to step 1:
63 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 63

Let's proceed to step 2:
63 goes into 51 0 times with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Include the next digit (7) from the dividend after 51, then repeat: 517 / 63

Moving on to step 3:
If we divide 517 by 63, we get 8 and a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 504 from 517 and we're left with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 63

Step 4:
If we divide 138 by 63, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtract 126 from 138 to get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 63

Moving on to step 5:
63 can be fit into 123 1 times, resulting in a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 821.0
The remainder is 60 after subtracting 63 from 123.
Grab the next digit (0) from the dividend, add it to 60, then carry on: 600 / 63

Moving on to step 6:
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: 8219.0
Subtract 567 from 600 to 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 7:
The number 63 fits into 330 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 8219.5
Subtract 315 from 330 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
63 goes into 150 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 8219.52
Deduct 126 from 150 and we're left 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.

Let's proceed to step 9:
240 divided by 63 is 3 with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 8219.523
Deduct 189 from 240 and we're left 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.

Step 10:
63 goes into 510 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 8219.5238
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.

Step 11:
63 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 8219.5238
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.

Step 12:
When dividing 600 by 63, we get 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 8219.523809
Deduct 567 from 600 and we're left 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 13:
63 goes into 330 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 8219.5238095
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.

Moving on to step 14:
If we divide 150 by 63, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 8219.52380952
Deduct 126 from 150 and we're left 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.

After the division, we end up with 8219.52380952 and a remainder of 2.4e-08.
