We look at the division of 48553 by 63 
The aim is to understand the frequency of 63 in 48553.

On to step 1:
If we divide 4 by 63, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 63

Let's proceed to step 2:
If we divide 48 by 63, we get 0 and a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 63

Advancing to step 3:
63 goes into 485 7 times with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 44 after subtracting 441 from 485.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 63

Step 4:
445 divided by 63 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 77.0
Subtract 441 from 445 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 63

Going ahead to step 5:
When dividing 43 by 63, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 770.0
The remainder is 43 after subtracting 0 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 6:
63 can be fit into 430 6 times, resulting in a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 770.6
The remainder is 52 after subtracting 378 from 430.
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 7:
If we divide 520 by 63, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 770.68
Subtract 504 from 520 to 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.

Advancing to step 8:
160 divided by 63 is 2 with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 770.682
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
If we divide 340 by 63, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 770.6825
Subtract 315 from 340 to 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.

Let's proceed to step 10:
63 goes into 250 3 times with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 770.68253
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.

On to step 11:
63 goes into 610 9 times with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 770.682539
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.

On to step 12:
When dividing 430 by 63, we get 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 770.6825396
Subtracting 378 from 430 leaves us 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.

Step 13:
When dividing 520 by 63, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 770.68253968
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.

The quotient of the division is 770.68253968, and the remainder is 1.6e-08.
