We look at the division of 787223 by 63 
The aim is to understand the frequency of 63 in 787223.

Let's proceed to step 1:
63 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 63

Advancing to step 2:
If we divide 78 by 63, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 15 after subtracting 63 from 78.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 63

Moving on to step 3:
If we divide 157 by 63, we get 2 and a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 126 from 157, we get 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 63

Going ahead to step 4:
312 divided by 63 is 4 with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we take 252 away from 312, we end up with 60.
Include the next digit (2) from the dividend after 60, then repeat: 602 / 63

Let's proceed to step 5:
The number 63 fits into 602 9 times, leaving a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 1249.0
The remainder is 35 after subtracting 567 from 602.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 63

On to step 6:
63 goes into 353 5 times with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 12495.0
If we subtract 315 from 353, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
The number 63 fits into 380 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 12495.6
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
The number 63 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 12495.6
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
63 goes into 200 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 12495.603
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
When dividing 110 by 63, we get 1 with a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 12495.6031
Deduct 63 from 110 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 11:
470 divided by 63 is 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 12495.60317
Deduct 441 from 470 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 12:
If we divide 290 by 63, we get 4 and a remainder of 38.
The next digit of our result is 4. 
Result so far: 12495.603174
Subtracting 252 from 290 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
If we divide 380 by 63, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 12495.6031746
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
63 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 12495.6031746
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 12495.6031746, with a leftover of 2e-08.
