We look at the division of 386748 by 63 
The aim is to understand the frequency of 63 in 386748.

Let's proceed to step 1:
3 divided by 63 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 63

Let's proceed to step 2:
The number 63 fits into 38 0 times, leaving a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 63

Let's proceed to step 3:
63 goes into 386 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 378 from 386, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 63

On to step 4:
When dividing 87 by 63, we get 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we subtract 63 from 87, we get 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 63

On to step 5:
If we divide 244 by 63, we get 3 and a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 613.0
Subtract 189 from 244 to get 55.
Include the next digit (8) from the dividend after 55, then repeat: 558 / 63

Step 6:
If we divide 558 by 63, we get 8 and a remainder of 54.
The next digit of our result is 8. 
Result so far: 6138.0
The remainder is 54 after subtracting 504 from 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
63 can be fit into 540 8 times, resulting in a remainder of 36.
The next digit of our result is 8. 
Result so far: 6138.8
Subtract 504 from 540 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
63 goes into 360 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 6138.85
Subtract 315 from 360 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
63 can be fit into 450 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 6138.857
Subtracting 441 from 450 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
90 divided by 63 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 6138.8571
If we take 63 away from 90, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 11:
270 divided by 63 is 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 6138.85714
If we take 252 away from 270, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
When dividing 180 by 63, we get 2 with a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 6138.857142
Deduct 126 from 180 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 13:
When dividing 540 by 63, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 6138.8571428
If we subtract 504 from 540, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
63 can be fit into 360 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 6138.85714285
If we subtract 315 from 360, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 6138.85714285, with a leftover of 4.5e-08.
