We look at the division of 20448555 by 63 
The aim is to understand the frequency of 63 in 20448555.

Let's proceed to step 1:
The number 63 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 63

Step 2:
63 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 63

Step 3:
If we divide 204 by 63, we get 3 and a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 189 from 204 to get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 63

On to step 4:
154 divided by 63 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 32.0
The remainder is 28 after subtracting 126 from 154.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 63

On to step 5:
If we divide 288 by 63, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 324.0
The remainder is 36 after subtracting 252 from 288.
Bring next digit (5) of the dividend behind the 36 and repeat the process: 365 / 63

Step 6:
The number 63 fits into 365 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3245.0
If we subtract 315 from 365, we get 50.
Take the next digit (5) from the dividend and append it to 50, then repeat: 505 / 63

Going ahead to step 7:
63 can be fit into 505 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 32458.0
If we take 504 away from 505, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 63

Moving on to step 8:
63 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 324580.0
Deduct 0 from 15 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
150 divided by 63 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 324580.2
Deduct 126 from 150 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
63 goes into 240 3 times with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 324580.23
If we take 189 away from 240, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 11:
The number 63 fits into 510 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 324580.238
Deduct 504 from 510 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
60 divided by 63 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 324580.238
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
If we divide 600 by 63, we get 9 and a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 324580.23809
If we subtract 567 from 600, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 14:
63 can be fit into 330 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 324580.238095
Subtract 315 from 330 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 15:
63 can be fit into 150 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 324580.2380952
Subtract 126 from 150 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 16:
The number 63 fits into 240 3 times, leaving a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 324580.23809523
If we take 189 away from 240, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 324580.23809523 and a remainder of 5.1e-08.
