We're dividing 908138 by 18 
Let's see how many times 18 fits into 908138.

Advancing to step 1:
9 divided by 18 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 18

Advancing to step 2:
If we divide 90 by 18, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 90 from 90 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 18

Moving on to step 3:
If we divide 8 by 18, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 18

On to step 4:
18 goes into 81 4 times with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 504.0
Deduct 72 from 81 and we're left with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 18

Going ahead to step 5:
If we divide 93 by 18, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 5045.0
If we subtract 90 from 93, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 18

Let's proceed to step 6:
When dividing 38 by 18, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 50452.0
The remainder is 2 after subtracting 36 from 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 18 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 50452.1
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
20 divided by 18 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 50452.11
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 50452.11 with a remaining 0.002.
