We look at the division of 178410 by 9 
Let's see how many times 9 fits into 178410.

Going ahead to step 1:
9 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 9

On to step 2:
When dividing 17 by 9, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 9 away from 17, we end up with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 9

On to step 3:
When dividing 88 by 9, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 81 from 88 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 9

Advancing to step 4:
9 goes into 74 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 198.0
Subtract 72 from 74 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 9

Step 5:
When dividing 21 by 9, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 1982.0
Subtract 18 from 21 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 9

Moving on to step 6:
9 goes into 30 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 19823.0
Deduct 27 from 30 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
9 goes into 30 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 19823.3
Subtract 27 from 30 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
If we divide 30 by 9, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 19823.33
If we subtract 27 from 30, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 19823.33 with a remaining 0.003.
