312339 ÷ 64 
The aim is to understand the frequency of 64 in 312339.

Going ahead to step 1:
If we divide 3 by 64, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 64

On to step 2:
When dividing 31 by 64, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 64

Let's proceed to step 3:
312 divided by 64 is 4 with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 256 from 312, we get 56.
Take the next digit (3) from the dividend and append it to 56, then repeat: 563 / 64

Going ahead to step 4:
64 goes into 563 8 times with a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
The remainder is 51 after subtracting 512 from 563.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 64

Advancing to step 5:
64 can be fit into 513 8 times, resulting in a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 488.0
Deduct 512 from 513 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 64

Step 6:
When dividing 19 by 64, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 4880.0
If we subtract 0 from 19, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
The number 64 fits into 190 2 times, leaving a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 4880.2
The remainder is 62 after subtracting 128 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 8:
64 goes into 620 9 times with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 4880.29
Deduct 576 from 620 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
64 can be fit into 440 6 times, resulting in a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 4880.296
The remainder is 56 after subtracting 384 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
When dividing 560 by 64, we get 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 4880.2968
If we take 512 away from 560, 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.

Going ahead to step 11:
When dividing 480 by 64, we get 7 with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 4880.29687
Deduct 448 from 480 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.

Going ahead to step 12:
320 divided by 64 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4880.296875
The remainder is 0 after subtracting 320 from 320.
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.
Write down 0 as next digit of the result. 
Result so far: 4880.296875
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.

Moving on to step 14:
If we divide 0 by 64, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4880.296875
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 4880.296875, with a leftover of 0.0.
