We look at the division of 654894 by 63 
The aim is to understand the frequency of 63 in 654894.

On to step 1:
63 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 63

Moving on to step 2:
If we divide 65 by 63, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 2 after subtracting 63 from 65.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 63

Moving on to step 3:
24 divided by 63 is 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 24, we end up with 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 63

Going ahead to step 4:
63 can be fit into 248 3 times, resulting in a remainder of 59.
The next digit of our result is 3. 
Result so far: 103.0
Subtract 189 from 248 to get 59.
Grab the next digit (9) from the dividend, add it to 59, then carry on: 599 / 63

Advancing to step 5:
599 divided by 63 is 9 with a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 1039.0
If we subtract 567 from 599, we get 32.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 63

Step 6:
If we divide 324 by 63, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 10395.0
Subtracting 315 from 324 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.

Advancing to step 7:
If we divide 90 by 63, we get 1 and a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 10395.1
Subtracting 63 from 90 leaves us 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.

Moving on to step 8:
When dividing 270 by 63, we get 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 10395.14
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.

Going ahead to step 9:
180 divided by 63 is 2 with a remainder of 54.
The next digit of our result is 2. 
Result so far: 10395.142
Subtract 126 from 180 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 10:
If we divide 540 by 63, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 10395.1428
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.

Step 11:
63 can be fit into 360 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 10395.14285
If we take 315 away from 360, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
450 divided by 63 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 10395.142857
Deduct 441 from 450 and we're left 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.

On to step 13:
The number 63 fits into 90 1 times, leaving a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 10395.1428571
Deduct 63 from 90 and we're left 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.

Let's proceed to step 14:
63 can be fit into 270 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 10395.14285714
Subtract 252 from 270 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 10395.14285714 with a remaining 1.8e-08.
