We look at the division of 429121 by 64 
The aim is to understand the frequency of 64 in 429121.

Advancing to step 1:
The number 64 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 64

Let's proceed to step 2:
If we divide 42 by 64, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 64

Going ahead to step 3:
64 goes into 429 6 times with a remainder of 45.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 384 from 429 leaves us with 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 64

Advancing to step 4:
When dividing 451 by 64, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
If we subtract 448 from 451, we get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 64

Step 5:
32 divided by 64 is 0 with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 670.0
If we subtract 0 from 32, we get 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 64

Step 6:
When dividing 321 by 64, we get 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 6705.0
The remainder is 1 after subtracting 320 from 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
64 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 6705.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 64 fits into 100 1 times, leaving a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 6705.01
If we subtract 64 from 100, 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.

Let's proceed to step 9:
If we divide 360 by 64, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 6705.015
The remainder is 40 after subtracting 320 from 360.
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 10:
The number 64 fits into 400 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 6705.0156
Subtract 384 from 400 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
64 goes into 160 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 6705.01562
If we subtract 128 from 160, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
If we divide 320 by 64, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6705.015625
Subtracting 320 from 320 leaves us 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 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6705.015625
If we subtract 0 from 0, 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 14:
If we divide 0 by 64, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 6705.015625
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.

In conclusion, the division gives 6705.015625 with a balance of 0.0.
