458781 divided by 64 
The aim is to understand the frequency of 64 in 458781.

On to step 1:
When dividing 4 by 64, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 64

Step 2:
45 divided by 64 is 0 with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 64

Advancing to step 3:
The number 64 fits into 458 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 448 from 458, we get 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 64

On to step 4:
The number 64 fits into 107 1 times, leaving a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we subtract 64 from 107, we get 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 64

Going ahead to step 5:
64 goes into 438 6 times with a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 716.0
Subtract 384 from 438 to get 54.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 64

Going ahead to step 6:
541 divided by 64 is 8 with a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 7168.0
Subtracting 512 from 541 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
When dividing 290 by 64, we get 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 7168.4
Deduct 256 from 290 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
64 can be fit into 340 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 7168.45
The remainder is 20 after subtracting 320 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
The number 64 fits into 200 3 times, leaving a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 7168.453
Deduct 192 from 200 and we're left 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.

On to step 10:
When dividing 80 by 64, we get 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 7168.4531
The remainder is 16 after subtracting 64 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
The number 64 fits into 160 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 7168.45312
Subtracting 128 from 160 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.

Going ahead to step 12:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7168.453125
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.

Moving on to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7168.453125
If we subtract 0 from 0, 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 14:
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: 7168.453125
If we subtract 0 from 0, 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.

Our division results in 7168.453125 with a remaining 0.0.
