We look at the division of 520773 by 64 
The aim is to understand the frequency of 64 in 520773.

Moving on to step 1:
5 divided by 64 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 64

Step 2:
If we divide 52 by 64, we get 0 and a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 64

Moving on to step 3:
When dividing 520 by 64, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 512 away from 520, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 64

Step 4:
64 can be fit into 87 1 times, resulting in a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 81.0
If we subtract 64 from 87, we get 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 64

On to step 5:
If we divide 237 by 64, we get 3 and a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 813.0
Subtract 192 from 237 to get 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 64

Let's proceed to step 6:
If we divide 453 by 64, we get 7 and a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 8137.0
Subtract 448 from 453 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 64, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 8137.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
64 can be fit into 500 7 times, resulting in a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 8137.07
Subtract 448 from 500 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
64 goes into 520 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 8137.078
If we take 512 away from 520, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
64 goes into 80 1 times with a remainder of 16.
The next digit of our result is 1. 
Result so far: 8137.0781
If we take 64 away from 80, 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.

Advancing to step 11:
When dividing 160 by 64, we get 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 8137.07812
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.

Moving on to step 12:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8137.078125
Subtract 320 from 320 to 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.

Step 13:
0 divided by 64 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8137.078125
Subtract 0 from 0 to 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 14:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8137.078125
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.

In conclusion, the division gives 8137.078125 with a balance of 0.0.
