We look at the division of 66226 by 63 
The aim is to understand the frequency of 63 in 66226.

On to step 1:
63 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 63

On to step 2:
66 divided by 63 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 3 after subtracting 63 from 66.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 63

Advancing to step 3:
32 divided by 63 is 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 32 after subtracting 0 from 32.
Include the next digit (2) from the dividend after 32, then repeat: 322 / 63

Let's proceed to step 4:
The number 63 fits into 322 5 times, leaving a remainder of 7.
The next digit of our result is 5. 
Result so far: 105.0
Deduct 315 from 322 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 63

Step 5:
63 can be fit into 76 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1051.0
Deduct 63 from 76 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 6:
The number 63 fits into 130 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 1051.2
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
63 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1051.2
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
400 divided by 63 is 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 1051.206
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
220 divided by 63 is 3 with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 1051.2063
If we subtract 189 from 220, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 10:
When dividing 310 by 63, we get 4 with a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 1051.20634
Subtracting 252 from 310 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
When dividing 580 by 63, we get 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 1051.206349
Deduct 567 from 580 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
63 goes into 130 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 1051.2063492
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
When dividing 40 by 63, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1051.2063492
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 1051.2063492 with a remaining 4e-08.
