We're dividing 259920 by 64 
We want to divide 259920 by 64.

On to step 1:
64 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 64

Going ahead to step 2:
64 can be fit into 25 0 times, resulting in a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 64

Going ahead to step 3:
64 goes into 259 4 times with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 256 from 259, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 64

Advancing to step 4:
64 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 39 to get 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 64

Step 5:
392 divided by 64 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 406.0
Subtract 384 from 392 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 64

Let's proceed to step 6:
If we divide 80 by 64, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 4061.0
Deduct 64 from 80 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
160 divided by 64 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 4061.2
Subtracting 128 from 160 leaves us 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.

Step 8:
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: 4061.25
The remainder is 0 after subtracting 320 from 320.
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:
When dividing 0 by 64, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4061.25
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.

On to step 10:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4061.25
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.

Our division results in 4061.25 with a remaining 0.0.
