We're dividing 526389 by 18 
We want to figure out the number of times 526389 can be divided by 18.

Step 1:
18 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 18

Advancing to step 2:
If we divide 52 by 18, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 36 from 52 and we're left with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 18

Advancing to step 3:
18 can be fit into 166 9 times, resulting in a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we subtract 162 from 166, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 18

Let's proceed to step 4:
18 can be fit into 43 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 292.0
The remainder is 7 after subtracting 36 from 43.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 18

Step 5:
78 divided by 18 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 2924.0
Subtract 72 from 78 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 18

Let's proceed to step 6:
The number 18 fits into 69 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 29243.0
The remainder is 15 after subtracting 54 from 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
The number 18 fits into 150 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 29243.8
Subtracting 144 from 150 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
When dividing 60 by 18, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 29243.83
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
When dividing 60 by 18, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 29243.833
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 29243.833 with a remainder of 0.0006.
