439616 ÷ 64 
We want to divide 439616 by 64.

On to step 1:
When dividing 4 by 64, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 64

Let's proceed to step 2:
If we divide 43 by 64, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 64

Let's proceed to step 3:
The number 64 fits into 439 6 times, leaving a remainder of 55.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 384 away from 439, we end up with 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 64

Let's proceed to step 4:
If we divide 556 by 64, we get 8 and a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Deduct 512 from 556 and we're left with 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 64

Moving on to step 5:
64 goes into 441 6 times with a remainder of 57.
Put 6 as the next digit of the answer. 
Result so far: 686.0
The remainder is 57 after subtracting 384 from 441.
Include the next digit (6) from the dividend after 57, then repeat: 576 / 64

Let's proceed to step 6:
The number 64 fits into 576 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 6869.0
Subtracting 576 from 576 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.

Advancing to step 7:
64 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6869.0
Subtracting 0 from 0 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.

Moving on to step 8:
0 divided by 64 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6869.0
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 6869.0, with a leftover of 0.0.
