72396457 divided by 320 
We want to divide 72396457 by 320.

Advancing to step 1:
320 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 320

Going ahead to step 2:
When dividing 72 by 320, we get 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Include the next digit (3) from the dividend after 72, then repeat: 723 / 320

Step 3:
723 divided by 320 is 2 with a remainder of 83.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 640 from 723 leaves us with 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 320

Let's proceed to step 4:
When dividing 839 by 320, we get 2 with a remainder of 199.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 640 from 839 to get 199.
Include the next digit (6) from the dividend after 199, then repeat: 1996 / 320

Step 5:
When dividing 1996 by 320, we get 6 with a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 226.0
If we subtract 1920 from 1996, we get 76.
Include the next digit (4) from the dividend after 76, then repeat: 764 / 320

Moving on to step 6:
The number 320 fits into 764 2 times, leaving a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 2262.0
If we subtract 640 from 764, we get 124.
Include the next digit (5) from the dividend after 124, then repeat: 1245 / 320

Advancing to step 7:
The number 320 fits into 1245 3 times, leaving a remainder of 285.
Write down 3 as next digit of the result. 
Result so far: 22623.0
Deduct 960 from 1245 and we're left with 285.
Grab the next digit (7) from the dividend, add it to 285, then carry on: 2857 / 320

Moving on to step 8:
When dividing 2857 by 320, we get 8 with a remainder of 297.
Put 8 as the next digit of the answer. 
Result so far: 226238.0
The remainder is 297 after subtracting 2560 from 2857.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Step 9:
2970 divided by 320 is 9 with a remainder of 90.
The number 9 becomes the next digit in our result. 
Result so far: 226238.9
Subtract 2880 from 2970 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
320 can be fit into 900 2 times, resulting in a remainder of 260.
Use 2 as the next digit of our solution. 
Result so far: 226238.92
If we subtract 640 from 900, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 11:
320 can be fit into 2600 8 times, resulting in a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 226238.928
If we take 2560 away from 2600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
If we divide 400 by 320, we get 1 and a remainder of 80.
Put 1 as the next digit of the answer. 
Result so far: 226238.9281
The remainder is 80 after subtracting 320 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
The number 320 fits into 800 2 times, leaving a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 226238.92812
The remainder is 160 after subtracting 640 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
If we divide 1600 by 320, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 226238.928125
Deduct 1600 from 1600 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 15:
0 divided by 320 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 226238.928125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 16:
320 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 226238.928125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 226238.928125 with a remainder of 0.0.
