We look at the division of 135967 by 63 
The aim is to understand the frequency of 63 in 135967.

Going ahead to step 1:
If we divide 1 by 63, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 63

Going ahead to step 2:
63 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 63

On to step 3:
When dividing 135 by 63, we get 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 126 from 135 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 63

On to step 4:
63 can be fit into 99 1 times, resulting in a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 63 from 99, we get 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 63

Moving on to step 5:
63 can be fit into 366 5 times, resulting in a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 215.0
The remainder is 51 after subtracting 315 from 366.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 63

Going ahead to step 6:
If we divide 517 by 63, we get 8 and a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 2158.0
Subtracting 504 from 517 leaves us 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.

Moving on to step 7:
130 divided by 63 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2158.2
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.

Let's proceed to step 8:
63 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 2158.2
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.

Going ahead to step 9:
If we divide 400 by 63, we get 6 and a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 2158.206
Subtracting 378 from 400 leaves us 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 10:
The number 63 fits into 220 3 times, leaving a remainder of 31.
The next digit of our result is 3. 
Result so far: 2158.2063
Subtracting 189 from 220 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
The number 63 fits into 310 4 times, leaving a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 2158.20634
The remainder is 58 after subtracting 252 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 12:
If we divide 580 by 63, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 2158.206349
The remainder is 13 after subtracting 567 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 13:
63 goes into 130 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2158.2063492
Subtract 126 from 130 to 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 14:
63 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2158.2063492
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.

The final outcome is 2158.2063492, with a leftover of 4e-08.
