439634 divided by 64 
We want to divide 439634 by 64.

On to step 1:
When dividing 4 by 64, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 64

Advancing to step 2:
When dividing 43 by 64, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 64

Let's proceed to step 3:
If we divide 439 by 64, we get 6 and 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.
Bring next digit (6) of the dividend behind the 55 and repeat the process: 556 / 64

Advancing to step 4:
64 can be fit into 556 8 times, resulting in a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 68.0
If we subtract 512 from 556, we get 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 64

Step 5:
When dividing 443 by 64, we get 6 with a remainder of 59.
The next digit of our result is 6. 
Result so far: 686.0
Deduct 384 from 443 and we're left with 59.
Include the next digit (4) from the dividend after 59, then repeat: 594 / 64

Let's proceed to step 6:
The number 64 fits into 594 9 times, leaving a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 6869.0
Subtract 576 from 594 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
64 goes into 180 2 times with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 6869.2
Subtracting 128 from 180 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
64 goes into 520 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 6869.28
Deduct 512 from 520 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
When dividing 80 by 64, we get 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 6869.281
If we subtract 64 from 80, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
64 goes into 160 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 6869.2812
Subtract 128 from 160 to get 32.
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 11:
The number 64 fits into 320 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6869.28125
Subtract 320 from 320 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.

On to step 12:
0 divided by 64 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6869.28125
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 13:
64 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6869.28125
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.

The final outcome is 6869.28125, with a leftover of 0.0.
