We're dividing 644937 by 72 
Our goal is to divide 644937 by 72.

Advancing to step 1:
72 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 72

Let's proceed to step 2:
64 divided by 72 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (4) of the dividend behind the 64 and repeat the process: 644 / 72

Moving on to step 3:
644 divided by 72 is 8 with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 576 from 644 and we're left with 68.
Take the next digit (9) from the dividend and append it to 68, then repeat: 689 / 72

Step 4:
689 divided by 72 is 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 89.0
Subtracting 648 from 689 leaves us with 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 72

Let's proceed to step 5:
413 divided by 72 is 5 with a remainder of 53.
The next digit of our result is 5. 
Result so far: 895.0
If we subtract 360 from 413, we get 53.
Include the next digit (7) from the dividend after 53, then repeat: 537 / 72

Moving on to step 6:
72 can be fit into 537 7 times, resulting in a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 8957.0
The remainder is 33 after subtracting 504 from 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
72 goes into 330 4 times with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 8957.4
Deduct 288 from 330 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
72 goes into 420 5 times with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 8957.45
If we take 360 away from 420, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
The number 72 fits into 600 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 8957.458
Subtract 576 from 600 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
240 divided by 72 is 3 with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 8957.4583
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
If we divide 240 by 72, we get 3 and a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 8957.45833
Deduct 216 from 240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 8957.45833 and a remainder of 2.4e-05.
