We're dividing 72488592 by 320 
We're looking to find how many times 320 goes into 72488592.

On to step 1:
The number 320 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 320

Let's proceed to step 2:
The number 320 fits into 72 0 times, leaving a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Append the next digit (4) from the dividend to 72 and continue with: 724 / 320

Moving on to step 3:
320 goes into 724 2 times with a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 640 from 724 leaves us with 84.
Append the next digit (8) from the dividend to 84 and continue with: 848 / 320

Step 4:
848 divided by 320 is 2 with a remainder of 208.
Write down 2 as next digit of the result. 
Result so far: 22.0
The remainder is 208 after subtracting 640 from 848.
Take the next digit (8) from the dividend and append it to 208, then repeat: 2088 / 320

On to step 5:
320 goes into 2088 6 times with a remainder of 168.
Put 6 as the next digit of the answer. 
Result so far: 226.0
Subtracting 1920 from 2088 leaves us with 168.
Include the next digit (5) from the dividend after 168, then repeat: 1685 / 320

Let's proceed to step 6:
The number 320 fits into 1685 5 times, leaving a remainder of 85.
The next digit of our result is 5. 
Result so far: 2265.0
The remainder is 85 after subtracting 1600 from 1685.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 320

Let's proceed to step 7:
320 can be fit into 859 2 times, resulting in a remainder of 219.
The number 2 becomes the next digit in our result. 
Result so far: 22652.0
Subtracting 640 from 859 leaves us with 219.
Take the next digit (2) from the dividend and append it to 219, then repeat: 2192 / 320

Moving on to step 8:
When dividing 2192 by 320, we get 6 with a remainder of 272.
Put 6 as the next digit of the answer. 
Result so far: 226526.0
If we subtract 1920 from 2192, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 9:
The number 320 fits into 2720 8 times, leaving a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 226526.8
If we take 2560 away from 2720, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
320 can be fit into 1600 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 226526.85
Subtracting 1600 from 1600 leaves us 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.

Going ahead to step 11:
When dividing 0 by 320, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 226526.85
Subtracting 0 from 0 leaves us 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 12:
If we divide 0 by 320, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 226526.85
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.

The final outcome is 226526.85, with a leftover of 0.0.
