We're dividing 180439 by 10 
We're looking to find how many times 10 goes into 180439.

On to step 1:
The number 10 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 10

Let's proceed to step 2:
18 divided by 10 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 8 after subtracting 10 from 18.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 10

Moving on to step 3:
The number 10 fits into 80 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 80 away from 80, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 10

Advancing to step 4:
When dividing 4 by 10, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 10

Let's proceed to step 5:
The number 10 fits into 43 4 times, leaving a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 1804.0
Deduct 40 from 43 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 10

Step 6:
When dividing 39 by 10, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 18043.0
The remainder is 9 after subtracting 30 from 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
90 divided by 10 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 18043.9
If we subtract 90 from 90, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18043.9
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 10 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18043.9
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 18043.9 with a remaining 0.0.
