We look at the division of 143229 by 64 
The aim is to understand the frequency of 64 in 143229.

On to step 1:
If we divide 1 by 64, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 64

Advancing to step 2:
64 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 64

On to step 3:
The number 64 fits into 143 2 times, leaving a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 128 away from 143, we end up with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 64

Let's proceed to step 4:
152 divided by 64 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 128 from 152 leaves us with 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 64

Moving on to step 5:
64 can be fit into 242 3 times, resulting in a remainder of 50.
The next digit of our result is 3. 
Result so far: 223.0
If we take 192 away from 242, we end up with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 64

On to step 6:
64 can be fit into 509 7 times, resulting in a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 2237.0
Subtracting 448 from 509 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 7:
610 divided by 64 is 9 with a remainder of 34.
The next digit of our result is 9. 
Result so far: 2237.9
Subtracting 576 from 610 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
If we divide 340 by 64, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 2237.95
The remainder is 20 after subtracting 320 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
The number 64 fits into 200 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 2237.953
If we subtract 192 from 200, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
64 can be fit into 80 1 times, resulting in a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 2237.9531
Deduct 64 from 80 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 64 fits into 160 2 times, leaving a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 2237.95312
Subtracting 128 from 160 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
64 can be fit into 320 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2237.953125
If we subtract 320 from 320, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2237.953125
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 14:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2237.953125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 2237.953125 with a remaining 0.0.
