We look at the division of 501550 by 3 
Let's see how many times 3 fits into 501550.

Moving on to step 1:
5 divided by 3 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 3 from 5, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 3

Moving on to step 2:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 18 away from 20, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Advancing to step 3:
If we divide 21 by 3, we get 7 and a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 167.0
Subtracting 21 from 21 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 3

Moving on to step 4:
5 divided by 3 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1671.0
Deduct 3 from 5 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

Going ahead to step 5:
The number 3 fits into 25 8 times, leaving a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 16718.0
Subtract 24 from 25 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 3

On to step 6:
If we divide 10 by 3, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 167183.0
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 167183.3
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 167183.33
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 167183.33 and a remainder of 0.001.
