We look at the division of 572683 by 64 
The aim is to understand the frequency of 64 in 572683.

On to step 1:
5 divided by 64 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 64

Moving on to step 2:
If we divide 57 by 64, we get 0 and a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Grab the next digit (2) from the dividend, add it to 57, then carry on: 572 / 64

Going ahead to step 3:
When dividing 572 by 64, we get 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 60 after subtracting 512 from 572.
Include the next digit (6) from the dividend after 60, then repeat: 606 / 64

On to step 4:
64 goes into 606 9 times with a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtracting 576 from 606 leaves us with 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 64

Step 5:
The number 64 fits into 308 4 times, leaving a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 894.0
Deduct 256 from 308 and we're left with 52.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 64

Going ahead to step 6:
523 divided by 64 is 8 with a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 8948.0
Subtract 512 from 523 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
64 can be fit into 110 1 times, resulting in a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 8948.1
Deduct 64 from 110 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
If we divide 460 by 64, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 8948.17
If we take 448 away from 460, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
When dividing 120 by 64, we get 1 with a remainder of 56.
The next digit of our result is 1. 
Result so far: 8948.171
Subtract 64 from 120 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.

Going ahead to step 10:
560 divided by 64 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 8948.1718
Subtracting 512 from 560 leaves us 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.

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: 8948.17187
If we take 448 away from 480, we end up 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 12:
64 can be fit into 320 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 8948.171875
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.

Going ahead to step 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8948.171875
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.

Going ahead to step 14:
64 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8948.171875
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.

The quotient of the division is 8948.171875, and the remainder is 0.0.
