We look at the division of 744624 by 64 
The aim is to understand the frequency of 64 in 744624.

Going ahead to step 1:
64 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 64

Step 2:
The number 64 fits into 74 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 64 from 74, we get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 64

On to step 3:
64 can be fit into 104 1 times, resulting in a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 64 from 104 and we're left with 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 64

Step 4:
When dividing 406 by 64, we get 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we subtract 384 from 406, we get 22.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 64

Going ahead to step 5:
The number 64 fits into 222 3 times, leaving a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 1163.0
The remainder is 30 after subtracting 192 from 222.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 64

Moving on to step 6:
The number 64 fits into 304 4 times, leaving a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 11634.0
If we subtract 256 from 304, 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.

Going ahead to step 7:
When dividing 480 by 64, we get 7 with a remainder of 32.
The next digit of our result is 7. 
Result so far: 11634.7
Deduct 448 from 480 and we're left 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.

Moving on to step 8:
64 goes into 320 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11634.75
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.

On to step 9:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11634.75
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.

Let's proceed to step 10:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11634.75
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 11634.75 and a remainder of 0.0.
