We're dividing 306958 by 18 
We want to divide 306958 by 18.

Let's proceed to step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 18

Let's proceed to step 2:
If we divide 30 by 18, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 18 from 30 and we're left with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 18

Step 3:
18 goes into 126 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 126 from 126 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 18

Advancing to step 4:
The number 18 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 170.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 18

Step 5:
18 goes into 95 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 1705.0
The remainder is 5 after subtracting 90 from 95.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 18

On to step 6:
58 divided by 18 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 17053.0
The remainder is 4 after subtracting 54 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
If we divide 40 by 18, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 17053.2
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
40 divided by 18 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 17053.22
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 17053.22, and the remainder is 0.004.
