We look at the division of 42499 by 64 
Let's see how many times 64 fits into 42499.

On to step 1:
The number 64 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 64

Moving on to step 2:
The number 64 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 64

Step 3:
64 goes into 424 6 times with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 384 from 424 leaves us with 40.
Bring next digit (9) of the dividend behind the 40 and repeat the process: 409 / 64

Moving on to step 4:
64 goes into 409 6 times with a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtract 384 from 409 to get 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 64

Moving on to step 5:
The number 64 fits into 259 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 664.0
Deduct 256 from 259 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 6:
When dividing 30 by 64, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 664.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
300 divided by 64 is 4 with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 664.04
Deduct 256 from 300 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
If we divide 440 by 64, we get 6 and a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 664.046
Subtracting 384 from 440 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
The number 64 fits into 560 8 times, leaving a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 664.0468
If we take 512 away from 560, 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:
480 divided by 64 is 7 with a remainder of 32.
The next digit of our result is 7. 
Result so far: 664.04687
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.

Let's proceed to step 11:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 664.046875
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.

Step 12:
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: 664.046875
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.

Going ahead to step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 664.046875
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.

In conclusion, the division gives 664.046875 with a balance of 0.0.
