667818 ÷ 64 
The aim is to understand the frequency of 64 in 667818.

Advancing to step 1:
When dividing 6 by 64, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 64

Moving on to step 2:
64 goes into 66 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 64 from 66 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 64

Moving on to step 3:
The number 64 fits into 27 0 times, leaving a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 27 leaves us with 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 64

Going ahead to step 4:
If we divide 278 by 64, we get 4 and a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 104.0
Deduct 256 from 278 and we're left with 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 64

Step 5:
If we divide 221 by 64, we get 3 and a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 1043.0
The remainder is 29 after subtracting 192 from 221.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 64

On to step 6:
If we divide 298 by 64, we get 4 and a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 10434.0
If we take 256 away from 298, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
The number 64 fits into 420 6 times, leaving a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 10434.6
Subtract 384 from 420 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
64 can be fit into 360 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 10434.65
If we take 320 away from 360, we end up 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.

Advancing to step 9:
If we divide 400 by 64, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 10434.656
The remainder is 16 after subtracting 384 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
The number 64 fits into 160 2 times, leaving a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 10434.6562
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.

Let's proceed to step 11:
When dividing 320 by 64, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10434.65625
Deduct 320 from 320 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 12:
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: 10434.65625
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 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: 10434.65625
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 10434.65625, with a leftover of 0.0.
