We look at the division of 238742 by 63 
The aim is to understand the frequency of 63 in 238742.

Moving on 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.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 63

Going ahead to step 2:
63 can be fit into 23 0 times, resulting in a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 63

Going ahead to step 3:
63 can be fit into 238 3 times, resulting in a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 189 from 238 leaves us with 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 63

Moving on to step 4:
63 goes into 497 7 times with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtract 441 from 497 to get 56.
Fetch the next digit (4) from the dividend, attach it to 56 and continue: 564 / 63

Advancing to step 5:
When dividing 564 by 63, we get 8 with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 378.0
Deduct 504 from 564 and we're left with 60.
Take the next digit (2) from the dividend and append it to 60, then repeat: 602 / 63

Let's proceed to step 6:
602 divided by 63 is 9 with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 3789.0
The remainder is 35 after subtracting 567 from 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
When dividing 350 by 63, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 3789.5
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
63 goes into 350 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 3789.55
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 3789.55 with a remainder of 0.035.
