We look at the division of 40597 by 63 
The aim is to understand the frequency of 63 in 40597.

Going ahead to step 1:
The number 63 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 63

Let's proceed to step 2:
63 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 63

Moving on to step 3:
When dividing 405 by 63, we get 6 with a remainder of 27.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 378 from 405 leaves us with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 63

Moving on to step 4:
The number 63 fits into 279 4 times, leaving a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Deduct 252 from 279 and we're left with 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 63

Let's proceed to step 5:
63 goes into 277 4 times with a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 644.0
Subtracting 252 from 277 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 6:
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: 644.3
The remainder is 61 after subtracting 189 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 7:
If we divide 610 by 63, we get 9 and a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 644.39
Subtracting 567 from 610 leaves us 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.

Let's proceed to step 8:
The number 63 fits into 430 6 times, leaving a remainder of 52.
The next digit of our result is 6. 
Result so far: 644.396
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.

On to step 9:
When dividing 520 by 63, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 644.3968
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.

Moving on to step 10:
When dividing 160 by 63, we get 2 with a remainder of 34.
The next digit of our result is 2. 
Result so far: 644.39682
If we take 126 away from 160, we end up 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.

On to step 11:
63 can be fit into 340 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 644.396825
If we subtract 315 from 340, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
The number 63 fits into 250 3 times, leaving a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 644.3968253
Subtracting 189 from 250 leaves us 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:
610 divided by 63 is 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 644.39682539
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.

In conclusion, the division gives 644.39682539 with a balance of 4.3e-08.
