787312 ÷ 63 
The aim is to understand the frequency of 63 in 787312.

Step 1:
When dividing 7 by 63, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 63

Moving on to step 2:
The number 63 fits into 78 1 times, leaving 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.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 63

Step 3:
The number 63 fits into 157 2 times, leaving a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 126 from 157 leaves us with 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 63

Going ahead to step 4:
63 can be fit into 313 4 times, resulting in a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 124.0
Subtract 252 from 313 to get 61.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 63

Step 5:
When dividing 611 by 63, we get 9 with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 1249.0
If we take 567 away from 611, we end up with 44.
Append the next digit (2) from the dividend to 44 and continue with: 442 / 63

Advancing to step 6:
63 can be fit into 442 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 12497.0
If we take 441 away from 442, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 63 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 12497.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
63 can be fit into 100 1 times, resulting in a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 12497.01
If we subtract 63 from 100, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
63 can be fit into 370 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 12497.015
If we take 315 away from 370, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
63 goes into 550 8 times with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 12497.0158
Subtract 504 from 550 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
460 divided by 63 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 12497.01587
The remainder is 19 after subtracting 441 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 12:
When dividing 190 by 63, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 12497.015873
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
63 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 12497.015873
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
63 can be fit into 100 1 times, resulting in a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 12497.01587301
Deduct 63 from 100 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The quotient of the division is 12497.01587301, and the remainder is 3.7e-08.
