938668 ÷ 64 
The aim is to understand the frequency of 64 in 938668.

Let's proceed to step 1:
64 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 64

Moving on to step 2:
The number 64 fits into 93 1 times, leaving a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 64 away from 93, we end up with 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 64

Moving on to step 3:
64 goes into 298 4 times with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 256 from 298 and we're left with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 64

Moving on to step 4:
64 can be fit into 426 6 times, resulting in a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 146.0
If we take 384 away from 426, we end up with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 64

Going ahead to step 5:
64 goes into 426 6 times with a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 1466.0
Deduct 384 from 426 and we're left with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 64

Moving on to step 6:
If we divide 428 by 64, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 14666.0
The remainder is 44 after subtracting 384 from 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
The number 64 fits into 440 6 times, leaving a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 14666.6
Deduct 384 from 440 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
64 can be fit into 560 8 times, resulting in a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 14666.68
If we subtract 512 from 560, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
The number 64 fits into 480 7 times, leaving a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 14666.687
The remainder is 32 after subtracting 448 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
If we divide 320 by 64, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 14666.6875
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 11:
64 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14666.6875
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.

Going ahead to step 12:
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: 14666.6875
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.

After the division, we end up with 14666.6875 and a remainder of 0.0.
