We're dividing 276639 by 18 
We're looking to find how many times 18 goes into 276639.

On to step 1:
18 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 18

Let's proceed to step 2:
If we divide 27 by 18, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 18 from 27 and we're left with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 18

Moving on to step 3:
When dividing 96 by 18, we get 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 90 from 96 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 18

Going ahead to step 4:
18 goes into 66 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Subtracting 54 from 66 leaves us with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 18

Moving on to step 5:
18 can be fit into 123 6 times, resulting in a remainder of 15.
The next digit of our result is 6. 
Result so far: 1536.0
Deduct 108 from 123 and we're left with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 18

Moving on to step 6:
18 goes into 159 8 times with a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 15368.0
If we subtract 144 from 159, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
When dividing 150 by 18, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 15368.8
Deduct 144 from 150 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.

Moving on to step 8:
18 can be fit into 60 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 15368.83
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
18 can be fit into 60 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 15368.833
Subtracting 54 from 60 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.

The quotient of the division is 15368.833, and the remainder is 0.0006.
