We look at the division of 67589 by 18 
Let's see how many times 18 fits into 67589.

Advancing to step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 18

Moving on to step 2:
18 goes into 67 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 54 from 67 to get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 18

Going ahead to step 3:
When dividing 135 by 18, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 126 from 135, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 18

Moving on to step 4:
18 goes into 98 5 times with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 375.0
If we subtract 90 from 98, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 18

On to step 5:
18 can be fit into 89 4 times, resulting in a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 3754.0
Deduct 72 from 89 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 6:
18 can be fit into 170 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 3754.9
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
80 divided by 18 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 3754.94
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 3754.944
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 3754.944 and a remainder of 0.0008.
