We look at the division of 309104 by 83 
We're looking to find how many times 83 goes into 309104.

On to step 1:
83 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 83

Advancing to step 2:
If we divide 30 by 83, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 83

Step 3:
When dividing 309 by 83, we get 3 with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 60 after subtracting 249 from 309.
Bring next digit (1) of the dividend behind the 60 and repeat the process: 601 / 83

On to step 4:
The number 83 fits into 601 7 times, leaving a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtract 581 from 601 to get 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 83

Moving on to step 5:
83 can be fit into 200 2 times, resulting in a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 372.0
Subtract 166 from 200 to get 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 83

Let's proceed to step 6:
When dividing 344 by 83, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 3724.0
Subtract 332 from 344 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.

Advancing to step 7:
83 goes into 120 1 times with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 3724.1
The remainder is 37 after subtracting 83 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 8:
If we divide 370 by 83, we get 4 and a remainder of 38.
The next digit of our result is 4. 
Result so far: 3724.14
Subtracting 332 from 370 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
The number 83 fits into 380 4 times, leaving a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 3724.144
Subtract 332 from 380 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 3724.144, and the remainder is 0.0048.
