Let's divide 640357 by 72
We're looking to find how many times 72 goes into 640357.

Moving on 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
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
The remainder is 64 after subtracting 0 from 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 72

Moving on to step 3:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 576 from 640 and we're left with 64.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 72

Let's proceed to step 4:
72 goes into 643 8 times with a remainder of 67.
Write down 8 as next digit of the result. 
Result so far: 88.0
The remainder is 67 after subtracting 576 from 643.
Append the next digit (5) from the dividend to 67 and continue with: 675 / 72

Advancing to step 5:
When dividing 675 by 72, we get 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 889.0
Deduct 648 from 675 and we're left with 27.
Include the next digit (7) from the dividend after 27, then repeat: 277 / 72

Step 6:
72 goes into 277 3 times with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 8893.0
The remainder is 61 after subtracting 216 from 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 7:
The number 72 fits into 610 8 times, leaving a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 8893.8
The remainder is 34 after subtracting 576 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
340 divided by 72 is 4 with a remainder of 52.
The next digit of our result is 4. 
Result so far: 8893.84
Subtracting 288 from 340 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.

Going ahead to step 9:
520 divided by 72 is 7 with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 8893.847
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
If we divide 160 by 72, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 8893.8472
Subtract 144 from 160 to 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 11:
If we divide 160 by 72, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 8893.84722
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 8893.84722 with a remaining 1.6e-05.
