We're dividing 900064 by 72 
We want to figure out the number of times 900064 can be divided by 72.

Step 1:
72 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 72

Let's proceed to step 2:
When dividing 90 by 72, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 72 from 90, we get 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 72

Let's proceed to step 3:
If we divide 180 by 72, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 144 from 180 and we're left with 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 72

Moving on to step 4:
The number 72 fits into 360 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 125.0
If we subtract 360 from 360, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 72

Going ahead to step 5:
If we divide 6 by 72, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 1250.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 72

Step 6:
The number 72 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 12500.0
Deduct 0 from 64 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
The number 72 fits into 640 8 times, leaving a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 12500.8
Deduct 576 from 640 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 8:
72 can be fit into 640 8 times, resulting in a remainder of 64.
The next digit of our result is 8. 
Result so far: 12500.88
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 12500.88 and a remainder of 0.064.
