Let's divide 2399 by 63
The aim is to understand the frequency of 63 in 2399.

Advancing to step 1:
If we divide 2 by 63, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 63

Advancing to step 2:
When dividing 23 by 63, we get 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 63

Let's proceed to step 3:
63 can be fit into 239 3 times, resulting in a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 189 from 239 leaves us with 50.
Grab the next digit (9) from the dividend, add it to 50, then carry on: 509 / 63

Let's proceed to step 4:
63 can be fit into 509 8 times, resulting in a remainder of 5.
The next digit of our result is 8. 
Result so far: 38.0
The remainder is 5 after subtracting 504 from 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 5:
When dividing 50 by 63, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 38.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 6:
If we divide 500 by 63, we get 7 and a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 38.07
Subtracting 441 from 500 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
63 goes into 590 9 times with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 38.079
Subtracting 567 from 590 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 8:
63 can be fit into 230 3 times, resulting in a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 38.0793
If we subtract 189 from 230, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
410 divided by 63 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 38.07936
Deduct 378 from 410 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
The number 63 fits into 320 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 38.079365
The remainder is 5 after subtracting 315 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
63 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 38.079365
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
500 divided by 63 is 7 with a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 38.07936507
The remainder is 59 after subtracting 441 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Our division results in 38.07936507 with a remaining 5.9e-08.
