We divide 642324 by 72
We're looking to find how many times 72 goes into 642324.

Step 1:
6 divided by 72 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 72

Moving on to step 2:
64 divided by 72 is 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 72

On to step 3:
72 goes into 642 8 times with a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 576 from 642 to get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 72

Let's proceed to step 4:
If we divide 663 by 72, we get 9 and a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we take 648 away from 663, we end up with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 72

Step 5:
72 goes into 152 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 892.0
If we take 144 away from 152, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 72

Step 6:
When dividing 84 by 72, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 8921.0
Subtract 72 from 84 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.

Let's proceed to step 7:
72 can be fit into 120 1 times, resulting in a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 8921.1
If we subtract 72 from 120, we 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.

Moving on to step 8:
72 can be fit into 480 6 times, resulting in a remainder of 48.
The next digit of our result is 6. 
Result so far: 8921.16
If we subtract 432 from 480, we 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.

Going ahead to step 9:
When dividing 480 by 72, we get 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 8921.166
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 8921.166, with a leftover of 0.0048.
