We look at the division of 389890 by 64 
The aim is to understand the frequency of 64 in 389890.

Moving on to step 1:
If we divide 3 by 64, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 64

Step 2:
64 goes into 38 0 times with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 64

Advancing to step 3:
If we divide 389 by 64, we get 6 and a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 384 from 389 leaves us with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 64

Let's proceed to step 4:
64 can be fit into 58 0 times, resulting in a remainder of 58.
The next digit of our result is 0. 
Result so far: 60.0
If we subtract 0 from 58, we get 58.
Include the next digit (9) from the dividend after 58, then repeat: 589 / 64

Let's proceed to step 5:
If we divide 589 by 64, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 609.0
The remainder is 13 after subtracting 576 from 589.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 64

Moving on to step 6:
64 can be fit into 130 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 6092.0
If we subtract 128 from 130, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 64, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 6092.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 64 fits into 200 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 6092.03
If we take 192 away from 200, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
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: 6092.031
Subtracting 64 from 80 leaves us 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.

Moving on to step 10:
160 divided by 64 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 6092.0312
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.

Step 11:
320 divided by 64 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 6092.03125
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.

Let's proceed to step 12:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6092.03125
Subtracting 0 from 0 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.

Step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6092.03125
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 6092.03125 with a balance of 0.0.
