409798 ÷ 64 
The aim is to understand the frequency of 64 in 409798.

Let's proceed to step 1:
64 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 64

Step 2:
The number 64 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 64

Going ahead to step 3:
64 can be fit into 409 6 times, resulting in a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 25 after subtracting 384 from 409.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 64

Going ahead to step 4:
64 goes into 257 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we take 256 away from 257, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 64

On to step 5:
64 can be fit into 19 0 times, resulting in a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 640.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 64

On to step 6:
64 can be fit into 198 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 6403.0
The remainder is 6 after subtracting 192 from 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
When dividing 60 by 64, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 6403.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
When dividing 600 by 64, we get 9 with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 6403.09
Deduct 576 from 600 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
240 divided by 64 is 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 6403.093
If we take 192 away from 240, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
64 goes into 480 7 times with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 6403.0937
If we subtract 448 from 480, we 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 11:
320 divided by 64 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 6403.09375
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.

Step 12:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6403.09375
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.

On to step 13:
64 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 6403.09375
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 quotient of the division is 6403.09375, and the remainder is 0.0.
