We're dividing 30673 by 75 
We're looking to find how many times 75 goes into 30673.

Step 1:
If we divide 3 by 75, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 75

On to step 2:
When dividing 30 by 75, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 75

Step 3:
75 can be fit into 306 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 300 from 306 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 75

Advancing to step 4:
67 divided by 75 is 0 with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
The remainder is 67 after subtracting 0 from 67.
Grab the next digit (3) from the dividend, add it to 67, then carry on: 673 / 75

Let's proceed to step 5:
673 divided by 75 is 8 with a remainder of 73.
The number 8 becomes the next digit in our result. 
Result so far: 408.0
Deduct 600 from 673 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 6:
75 goes into 730 9 times with a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 408.9
Subtracting 675 from 730 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 7:
If we divide 550 by 75, we get 7 and a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 408.97
Subtracting 525 from 550 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 408.973
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 408.9733
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 408.9733 and a remainder of 0.00025.
