We're dividing 64039 by 72 
We want to figure out the number of times 64039 can be divided by 72.

On to step 1:
If we divide 6 by 72, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 72

Moving on to step 2:
72 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 72

Let's proceed to step 3:
The number 72 fits into 640 8 times, leaving a remainder of 64.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 576 from 640 and we're left with 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 72

Step 4:
72 can be fit into 643 8 times, resulting in a remainder of 67.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
If we subtract 576 from 643, we get 67.
Append the next digit (9) from the dividend to 67 and continue with: 679 / 72

Advancing to step 5:
72 can be fit into 679 9 times, resulting in a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 889.0
If we take 648 away from 679, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 6:
72 can be fit into 310 4 times, resulting in a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 889.4
If we subtract 288 from 310, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
The number 72 fits into 220 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 889.43
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
When dividing 40 by 72, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 889.43
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 72, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 889.4305
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
If we divide 400 by 72, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 889.43055
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 889.43055 with a remaining 4e-05.
