We look at the division of 792385 by 63 
The aim is to understand the frequency of 63 in 792385.

Step 1:
When dividing 7 by 63, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 63

On to step 2:
63 can be fit into 79 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 63 from 79 leaves us with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 63

Step 3:
The number 63 fits into 162 2 times, leaving a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 126 from 162 and we're left with 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 63

Going ahead to step 4:
63 can be fit into 363 5 times, resulting in a remainder of 48.
Put 5 as the next digit of the answer. 
Result so far: 125.0
The remainder is 48 after subtracting 315 from 363.
Grab the next digit (8) from the dividend, add it to 48, then carry on: 488 / 63

Moving on to step 5:
488 divided by 63 is 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 1257.0
The remainder is 47 after subtracting 441 from 488.
Bring next digit (5) of the dividend behind the 47 and repeat the process: 475 / 63

Moving on to step 6:
475 divided by 63 is 7 with a remainder of 34.
The next digit of our result is 7. 
Result so far: 12577.0
The remainder is 34 after subtracting 441 from 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
If we divide 340 by 63, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 12577.5
Deduct 315 from 340 and we're left 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.

Let's proceed to step 8:
If we divide 250 by 63, we get 3 and a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 12577.53
If we subtract 189 from 250, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 9:
The number 63 fits into 610 9 times, leaving a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 12577.539
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.

Advancing to step 10:
The number 63 fits into 430 6 times, leaving a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 12577.5396
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.

Let's proceed to step 11:
63 goes into 520 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 12577.53968
If we subtract 504 from 520, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
63 goes into 160 2 times with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 12577.539682
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
63 can be fit into 340 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 12577.5396825
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.

Step 14:
The number 63 fits into 250 3 times, leaving a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 12577.53968253
Subtract 189 from 250 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 12577.53968253 with a remaining 6.1e-08.
