We look at the division of 439579 by 64 
Let's see how many times 64 fits into 439579.

Advancing to step 1:
4 divided by 64 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 64

Step 2:
The number 64 fits into 43 0 times, leaving a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 64

On to step 3:
64 can be fit into 439 6 times, resulting in a remainder of 55.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 384 from 439 to get 55.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 64

On to step 4:
If we divide 555 by 64, we get 8 and a remainder of 43.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we subtract 512 from 555, we get 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 64

Let's proceed to step 5:
If we divide 437 by 64, we get 6 and a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 686.0
Subtracting 384 from 437 leaves us with 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 64

Going ahead to step 6:
539 divided by 64 is 8 with a remainder of 27.
The next digit of our result is 8. 
Result so far: 6868.0
If we subtract 512 from 539, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
When dividing 270 by 64, we get 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 6868.4
If we subtract 256 from 270, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
The number 64 fits into 140 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 6868.42
Subtract 128 from 140 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
64 goes into 120 1 times with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 6868.421
Deduct 64 from 120 and we're left 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.

Moving on to step 10:
If we divide 560 by 64, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 6868.4218
Subtract 512 from 560 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
64 goes into 480 7 times with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 6868.42187
Deduct 448 from 480 and we're left 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.

Advancing to step 12:
320 divided by 64 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6868.421875
If we take 320 away from 320, 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.

Going ahead to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6868.421875
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 14:
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: 6868.421875
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.

The final result is 6868.421875 with a remainder of 0.0.
