We divide 618320 by 64
The aim is to understand the frequency of 64 in 618320.

On to step 1:
If we divide 6 by 64, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 64

Moving on to step 2:
64 can be fit into 61 0 times, resulting in a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 64

On to step 3:
64 goes into 618 9 times with a remainder of 42.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 576 from 618 and we're left with 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 64

Step 4:
The number 64 fits into 423 6 times, leaving a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 96.0
Subtracting 384 from 423 leaves us with 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 64

Going ahead to step 5:
When dividing 392 by 64, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 966.0
Subtract 384 from 392 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 64

Step 6:
64 goes into 80 1 times with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 9661.0
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 7:
64 goes into 160 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 9661.2
Deduct 128 from 160 and we're left 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.

On to step 8:
When dividing 320 by 64, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 9661.25
Deduct 320 from 320 and we're left 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.

Let's proceed to step 9:
When dividing 0 by 64, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9661.25
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.

Advancing to step 10:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9661.25
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.

The final outcome is 9661.25, with a leftover of 0.0.
