We look at the division of 321604 by 74 
Let's see how many times 74 fits into 321604.

Going ahead to step 1:
When dividing 3 by 74, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 74

Moving on to step 2:
32 divided by 74 is 0 with a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 32, we end up with 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 74

Let's proceed to step 3:
74 goes into 321 4 times with a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 25 after subtracting 296 from 321.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 74

Let's proceed to step 4:
The number 74 fits into 256 3 times, leaving a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 222 from 256 and we're left with 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 74

Let's proceed to step 5:
If we divide 340 by 74, we get 4 and a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 434.0
If we subtract 296 from 340, we get 44.
Take the next digit (4) from the dividend and append it to 44, then repeat: 444 / 74

Going ahead to step 6:
The number 74 fits into 444 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 4346.0
Subtract 444 from 444 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.

Let's proceed to step 7:
When dividing 0 by 74, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4346.0
If we take 0 away from 0, we end up 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.

Moving on to step 8:
If we divide 0 by 74, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4346.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 4346.0 and a remainder of 0.0.
