Let's divide 493988 by 3
We want to divide 493988 by 3.

Advancing to step 1:
4 divided by 3 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 3 from 4, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 3

Step 2:
If we divide 19 by 3, we get 6 and a remainder of 1.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 18 from 19 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 3

Step 3:
3 can be fit into 13 4 times, resulting in a remainder of 1.
The next digit of our result is 4. 
Result so far: 164.0
Deduct 12 from 13 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 3

Advancing to step 4:
3 can be fit into 19 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 1646.0
Subtract 18 from 19 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 3

On to step 5:
When dividing 18 by 3, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 16466.0
Deduct 18 from 18 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Going ahead to step 6:
3 can be fit into 8 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 164662.0
Subtract 6 from 8 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
3 goes into 20 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 164662.6
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 164662.66
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 164662.66 with a balance of 0.002.
