We're dividing 173493 by 3 
We're looking to find how many times 3 goes into 173493.

Moving on to step 1:
When dividing 1 by 3, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 3

On to step 2:
If we divide 17 by 3, we get 5 and a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 15 from 17 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 3

Going ahead to step 3:
23 divided by 3 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we subtract 21 from 23, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 3

Step 4:
When dividing 24 by 3, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 578.0
If we take 24 away from 24, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Moving on to step 5:
If we divide 9 by 3, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 5783.0
Subtract 9 from 9 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 3

Step 6:
If we divide 3 by 3, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 57831.0
Subtract 3 from 3 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.

On to step 7:
0 divided by 3 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 57831.0
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.

Moving on to step 8:
0 divided by 3 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 57831.0
If we subtract 0 from 0, 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.

Our division results in 57831.0 with a remaining 0.0.
