640292 ÷ 72 
We're looking to find how many times 72 goes into 640292.

Going ahead to 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
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 72

On to step 2:
72 can be fit into 64 0 times, resulting in a remainder of 64.
The next digit of our result is 0. 
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

Going ahead to step 3:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 576 from 640 and we're left with 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 72

Step 4:
72 goes into 642 8 times with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtract 576 from 642 to get 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 72

Advancing to step 5:
The number 72 fits into 669 9 times, leaving a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 889.0
The remainder is 21 after subtracting 648 from 669.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 72

Advancing to step 6:
72 goes into 212 2 times with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 8892.0
Subtract 144 from 212 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
If we divide 680 by 72, we get 9 and a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 8892.9
The remainder is 32 after subtracting 648 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
320 divided by 72 is 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 8892.94
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
72 can be fit into 320 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 8892.944
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 8892.944 with a remaining 0.0032.
