Let's divide 519646 by 64
The aim is to understand the frequency of 64 in 519646.

Let's proceed to step 1:
If we divide 5 by 64, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 64

Going ahead to step 2:
The number 64 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 64

Moving on to step 3:
519 divided by 64 is 8 with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 512 from 519 leaves us with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 64

On to step 4:
76 divided by 64 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Subtracting 64 from 76 leaves us with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 64

Advancing to step 5:
If we divide 124 by 64, we get 1 and a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 811.0
Deduct 64 from 124 and we're left with 60.
Append the next digit (6) from the dividend to 60 and continue with: 606 / 64

Let's proceed to step 6:
64 goes into 606 9 times with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 8119.0
If we take 576 away from 606, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
The number 64 fits into 300 4 times, leaving a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 8119.4
Subtracting 256 from 300 leaves us 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.

Step 8:
If we divide 440 by 64, we get 6 and a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 8119.46
Subtract 384 from 440 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
If we divide 560 by 64, we get 8 and a remainder of 48.
The next digit of our result is 8. 
Result so far: 8119.468
The remainder is 48 after subtracting 512 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
When dividing 480 by 64, we get 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 8119.4687
Subtracting 448 from 480 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.

On to step 11:
64 can be fit into 320 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8119.46875
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 12:
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: 8119.46875
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.

Step 13:
0 divided by 64 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8119.46875
Deduct 0 from 0 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.

The final outcome is 8119.46875, with a leftover of 0.0.
