We look at the division of 383861 by 63 
The aim is to understand the frequency of 63 in 383861.

On to step 1:
63 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 63

Moving on to step 2:
When dividing 38 by 63, we get 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Bring next digit (3) of the dividend behind the 38 and repeat the process: 383 / 63

Moving on to step 3:
63 goes into 383 6 times with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 5 after subtracting 378 from 383.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 63

Going ahead to step 4:
The number 63 fits into 58 0 times, leaving a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
The remainder is 58 after subtracting 0 from 58.
Include the next digit (6) from the dividend after 58, then repeat: 586 / 63

Let's proceed to step 5:
63 can be fit into 586 9 times, resulting in a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 609.0
Subtracting 567 from 586 leaves us with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 63

Advancing to step 6:
If we divide 191 by 63, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 6093.0
The remainder is 2 after subtracting 189 from 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
The number 63 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 6093.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 63, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 6093.03
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
63 goes into 110 1 times with a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 6093.031
If we take 63 away from 110, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 10:
63 can be fit into 470 7 times, resulting in a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 6093.0317
Subtracting 441 from 470 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
If we divide 290 by 63, we get 4 and a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 6093.03174
If we take 252 away from 290, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
When dividing 380 by 63, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 6093.031746
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
63 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 6093.031746
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
When dividing 200 by 63, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 6093.03174603
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 6093.03174603, with a leftover of 1.1e-08.
