We're dividing 400736 by 64 
The aim is to understand the frequency of 64 in 400736.

Going ahead to step 1:
64 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 64

Moving on to step 2:
64 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 64

Going ahead to step 3:
When dividing 400 by 64, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 384 from 400 to get 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 64

Let's proceed to step 4:
The number 64 fits into 167 2 times, leaving a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Subtracting 128 from 167 leaves us with 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 64

Step 5:
The number 64 fits into 393 6 times, leaving a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 626.0
Subtracting 384 from 393 leaves us with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 64

Going ahead to step 6:
64 can be fit into 96 1 times, resulting in a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 6261.0
Subtract 64 from 96 to get 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 7:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6261.5
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.

Step 8:
If we divide 0 by 64, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6261.5
If we take 0 away from 0, we end up 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.

Let's proceed to step 9:
If we divide 0 by 64, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6261.5
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.

The final result is 6261.5 with a remainder of 0.0.
