1904 divided by 328 is 5 with a remainder of 264.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 1640 from 1904 and we're left with 264.
Fetch the next digit (0) from the dividend, attach it to 264 and continue: 2640 / 328

Moving on to step 5:
The number 328 fits into 2640 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
Deduct 2624 from 2640 and we're left with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 328

Moving on to step 6:
163 divided by 328 is 0 with a remainder of 163.
Put 0 as the next digit of the answer. 
Result so far: 1580.0
The remainder is 163 after subtracting 0 from 163.
Bring next digit (7) of the dividend behind the 163 and repeat the process: 1637 / 328

Going ahead to step 7:
The number 328 fits into 1637 4 times, leaving a remainder of 325.
Put 4 as the next digit of the answer. 
Result so far: 15804.0
Subtract 1312 from 1637 to get 325.
Grab the next digit (4) from the dividend, add it to 325, then carry on: 3254 / 328

Step 8:
If we divide 3254 by 328, we get 9 and a remainder of 302.
Record the quotient 9 as the next digit in the result. 
Result so far: 158049.0
If we subtract 2952 from 3254, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 9:
When dividing 3020 by 328, we get 9 with a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 158049.9
If we subtract 2952 from 3020, we 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.

Step 10:
When dividing 680 by 328, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 158049.92
The remainder is 24 after subtracting 656 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
240 divided by 328 is 0 with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 158049.92
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
328 can be fit into 2400 7 times, resulting in a remainder of 104.
Use 7 as the next digit of our solution. 
Result so far: 158049.9207
Subtract 2296 from 2400 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 13:
When dividing 1040 by 328, we get 3 with a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 158049.92073
Subtract 984 from 1040 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
328 can be fit into 560 1 times, resulting in a remainder of 232.
The number 1 becomes the next digit in our result. 
Result so far: 158049.920731
Subtract 328 from 560 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 15:
2320 divided by 328 is 7 with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 158049.9207317
Subtract 2296 from 2320 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 16:
The number 328 fits into 240 0 times, leaving a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 158049.9207317
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

In conclusion, the division gives 158049.9207317 with a balance of 2.4e-07.
