511912 divided by 64 
The aim is to understand the frequency of 64 in 511912.

Step 1:
64 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 64

On to step 2:
64 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 64

Step 3:
The number 64 fits into 511 7 times, leaving a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 63 after subtracting 448 from 511.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 64

Going ahead to step 4:
The number 64 fits into 639 9 times, leaving a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
The remainder is 63 after subtracting 576 from 639.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 64

Let's proceed to step 5:
631 divided by 64 is 9 with a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 799.0
Subtract 576 from 631 to get 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 64

Advancing to step 6:
64 goes into 552 8 times with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 7998.0
Deduct 512 from 552 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
If we divide 400 by 64, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 7998.6
If we take 384 away from 400, we end up 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 8:
64 goes into 160 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 7998.62
The remainder is 32 after subtracting 128 from 160.
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 9:
64 goes into 320 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 7998.625
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.

On to step 10:
64 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7998.625
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.

Moving on to step 11:
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: 7998.625
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 outcome is 7998.625, with a leftover of 0.0.
