Let's divide 239640 by 64
We want to figure out the number of times 239640 can be divided by 64.

Going ahead to step 1:
2 divided by 64 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 64

Advancing to step 2:
The number 64 fits into 23 0 times, leaving a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 64

Advancing to step 3:
64 goes into 239 3 times with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 47 after subtracting 192 from 239.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 64

Step 4:
64 goes into 476 7 times with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 28 after subtracting 448 from 476.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 64

On to step 5:
The number 64 fits into 284 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 374.0
Subtract 256 from 284 to get 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 64

On to step 6:
64 goes into 280 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 3744.0
The remainder is 24 after subtracting 256 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
240 divided by 64 is 3 with a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 3744.3
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.

Moving on to step 8:
The number 64 fits into 480 7 times, leaving a remainder of 32.
The next digit of our result is 7. 
Result so far: 3744.37
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.

Going ahead to step 9:
320 divided by 64 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3744.375
Subtracting 320 from 320 leaves us 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.

Going ahead to step 10:
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: 3744.375
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.

Advancing to step 11:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3744.375
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 outcome is 3744.375, with a leftover of 0.0.
