If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 328

Moving on to step 2:
The number 328 fits into 72 0 times, leaving a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Take the next digit (3) from the dividend and append it to 72, then repeat: 723 / 328

Going ahead to step 3:
The number 328 fits into 723 2 times, leaving a remainder of 67.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 656 from 723 and we're left with 67.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 328

Let's proceed to step 4:
When dividing 679 by 328, we get 2 with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 656 from 679 to get 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 328

On to step 5:
328 goes into 230 0 times with a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 220.0
If we subtract 0 from 230, we get 230.
Take the next digit (5) from the dividend and append it to 230, then repeat: 2305 / 328

On to step 6:
If we divide 2305 by 328, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 2207.0
Deduct 2296 from 2305 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 328

Moving on to step 7:
The number 328 fits into 97 0 times, leaving a remainder of 97.
The next digit of our result is 0. 
Result so far: 22070.0
Subtract 0 from 97 to get 97.
Grab the next digit (1) from the dividend, add it to 97, then carry on: 971 / 328

Moving on to step 8:
The number 328 fits into 971 2 times, leaving a remainder of 315.
Put 2 as the next digit of the answer. 
Result so far: 220702.0
Subtracting 656 from 971 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 9:
The number 328 fits into 3150 9 times, leaving a remainder of 198.
Write down 9 as next digit of the result. 
Result so far: 220702.9
Deduct 2952 from 3150 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 10:
1980 divided by 328 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 220702.96
Subtract 1968 from 1980 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
328 goes into 120 0 times with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 220702.96
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
1200 divided by 328 is 3 with a remainder of 216.
The next digit of our result is 3. 
Result so far: 220702.9603
The remainder is 216 after subtracting 984 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 13:
The number 328 fits into 2160 6 times, leaving a remainder of 192.
Record the quotient 6 as the next digit in the result. 
Result so far: 220702.96036
If we subtract 1968 from 2160, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 14:
If we divide 1920 by 328, we get 5 and a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 220702.960365
If we subtract 1640 from 1920, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 15:
2800 divided by 328 is 8 with a remainder of 176.
Use 8 as the next digit of our solution. 
Result so far: 220702.9603658
Subtract 2624 from 2800 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 16:
If we divide 1760 by 328, we get 5 and a remainder of 120.
The next digit of our result is 5. 
Result so far: 220702.96036585
If we subtract 1640 from 1760, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 220702.96036585, with a leftover of 1.2e-07.
