We're dividing 964390 by 64 
The aim is to understand the frequency of 64 in 964390.

Going ahead to step 1:
When dividing 9 by 64, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 64

Moving on to step 2:
64 can be fit into 96 1 times, resulting in a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 64 from 96, we get 32.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 64

On to step 3:
When dividing 324 by 64, we get 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 4 after subtracting 320 from 324.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 64

Going ahead to step 4:
64 can be fit into 43 0 times, resulting in a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
If we subtract 0 from 43, we get 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 64

Advancing to step 5:
When dividing 439 by 64, we get 6 with a remainder of 55.
The number 6 becomes the next digit in our result. 
Result so far: 1506.0
Subtract 384 from 439 to get 55.
Fetch the next digit (0) from the dividend, attach it to 55 and continue: 550 / 64

Moving on to step 6:
64 goes into 550 8 times with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 15068.0
Subtract 512 from 550 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
380 divided by 64 is 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 15068.5
Subtracting 320 from 380 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
64 can be fit into 600 9 times, resulting in a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 15068.59
If we take 576 away from 600, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
64 goes into 240 3 times with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 15068.593
If we take 192 away from 240, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
If we divide 480 by 64, we get 7 and a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 15068.5937
If we take 448 away from 480, we end up 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.

Let's proceed to step 11:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15068.59375
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.

Advancing to step 12:
When dividing 0 by 64, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15068.59375
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.

Moving on to 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: 15068.59375
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.

The final result is 15068.59375 with a remainder of 0.0.
