We divide 666946 by 64
The aim is to understand the frequency of 64 in 666946.

Step 1:
6 divided by 64 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 64

On to step 2:
66 divided by 64 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 64 from 66 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 64

On to step 3:
When dividing 26 by 64, we get 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 26 after subtracting 0 from 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 64

Let's proceed to step 4:
64 can be fit into 269 4 times, resulting in a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 104.0
If we subtract 256 from 269, we get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 64

Going ahead to step 5:
64 can be fit into 134 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 1042.0
If we subtract 128 from 134, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 64

Moving on to step 6:
The number 64 fits into 66 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 10421.0
Subtracting 64 from 66 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
When dividing 20 by 64, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 10421.0
Subtracting 0 from 20 leaves us with 20.
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 8:
When dividing 200 by 64, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 10421.03
Subtract 192 from 200 to get 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 9:
64 goes into 80 1 times with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 10421.031
Subtract 64 from 80 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
64 goes into 160 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 10421.0312
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 11:
When dividing 320 by 64, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 10421.03125
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.

Advancing to step 12:
If we divide 0 by 64, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10421.03125
Subtracting 0 from 0 leaves us 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 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: 10421.03125
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.

After the division, we end up with 10421.03125 and a remainder of 0.0.
