We divide 113603 by 63
The aim is to understand the frequency of 63 in 113603.

Let's proceed to step 1:
When dividing 1 by 63, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 63

On to step 2:
The number 63 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 63

Going ahead to step 3:
If we divide 113 by 63, we get 1 and a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 50 after subtracting 63 from 113.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 63

Moving on to step 4:
63 can be fit into 506 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 504 away from 506, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 63

Let's proceed to step 5:
63 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 180.0
Subtracting 0 from 20 leaves us with 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 63

Let's proceed to step 6:
63 goes into 203 3 times with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 1803.0
The remainder is 14 after subtracting 189 from 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
When dividing 140 by 63, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 1803.2
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
63 can be fit into 140 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 1803.22
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 1803.22, with a leftover of 0.014.
