72572009 ÷ 343 
Let's see how many times 343 fits into 72572009.

Step 1:
When dividing 7 by 343, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 343

On to step 2:
343 can be fit into 72 0 times, resulting in a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 343

Let's proceed to step 3:
If we divide 725 by 343, we get 2 and a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 686 from 725, we get 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 343

Advancing to step 4:
343 goes into 397 1 times with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 343 from 397 to get 54.
Grab the next digit (2) from the dividend, add it to 54, then carry on: 542 / 343

Moving on to step 5:
343 can be fit into 542 1 times, resulting in a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 211.0
Subtract 343 from 542 to get 199.
Take the next digit (0) from the dividend and append it to 199, then repeat: 1990 / 343

Let's proceed to step 6:
343 goes into 1990 5 times with a remainder of 275.
The next digit of our result is 5. 
Result so far: 2115.0
Subtracting 1715 from 1990 leaves us with 275.
Take the next digit (0) from the dividend and append it to 275, then repeat: 2750 / 343

On to step 7:
343 can be fit into 2750 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 21158.0
If we take 2744 away from 2750, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 343

Let's proceed to step 8:
69 divided by 343 is 0 with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 211580.0
Subtracting 0 from 69 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 9:
343 can be fit into 690 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 211580.2
If we take 686 away from 690, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
When dividing 40 by 343, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 211580.2
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
343 can be fit into 400 1 times, resulting in a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 211580.201
If we subtract 343 from 400, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 12:
If we divide 570 by 343, we get 1 and a remainder of 227.
Put 1 as the next digit of the answer. 
Result so far: 211580.2011
Deduct 343 from 570 and we're left with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Our division results in 211580.2011 with a remaining 0.00227.
