84173 ÷ 18 
We're looking to find how many times 18 goes into 84173.

Moving on to step 1:
18 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 18

Going ahead to step 2:
When dividing 84 by 18, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 4.0
If we take 72 away from 84, we end up with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 18

Going ahead to step 3:
18 can be fit into 121 6 times, resulting in a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we subtract 108 from 121, we get 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 18

Step 4:
The number 18 fits into 137 7 times, leaving a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 467.0
Subtract 126 from 137 to get 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 18

Moving on to step 5:
18 goes into 113 6 times with a remainder of 5.
The next digit of our result is 6. 
Result so far: 4676.0
If we take 108 away from 113, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 6:
50 divided by 18 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 4676.2
The remainder is 14 after subtracting 36 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
When dividing 140 by 18, we get 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 4676.27
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
If we divide 140 by 18, we get 7 and a remainder of 14.
The next digit of our result is 7. 
Result so far: 4676.277
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 4676.277, and the remainder is 0.0014.
