We look at the division of 309289 by 18 
We want to divide 309289 by 18.

Moving on to step 1:
When dividing 3 by 18, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 18

Moving on to step 2:
18 goes into 30 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 12 after subtracting 18 from 30.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 18

Advancing to step 3:
The number 18 fits into 129 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 126 away from 129, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 18

On to step 4:
If we divide 32 by 18, we get 1 and a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 171.0
If we take 18 away from 32, we end up with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 18

Advancing to step 5:
18 goes into 148 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 1718.0
If we subtract 144 from 148, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 18

Advancing to step 6:
18 can be fit into 49 2 times, resulting in a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 17182.0
The remainder is 13 after subtracting 36 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
18 goes into 130 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 17182.7
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
18 can be fit into 40 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 17182.72
If we take 36 away from 40, we end up 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 9:
When dividing 40 by 18, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 17182.722
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 final outcome is 17182.722, with a leftover of 0.0004.
