We look at the division of 502401 by 3 
Our goal is to divide 502401 by 3.

Moving on to step 1:
3 goes into 5 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 3 away from 5, we end up with 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.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 2 after subtracting 18 from 20.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 3

Moving on to step 3:
When dividing 22 by 3, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 167.0
If we subtract 21 from 22, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 3

Moving on to step 4:
When dividing 14 by 3, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 1674.0
The remainder is 2 after subtracting 12 from 14.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Advancing to step 5:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 16746.0
Subtract 18 from 20 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Going ahead to step 6:
If we divide 21 by 3, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 167467.0
If we take 21 away from 21, we end up with 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 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 167467.0
Subtract 0 from 0 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.

Advancing to step 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 167467.0
Subtract 0 from 0 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.

The quotient of the division is 167467.0, and the remainder is 0.0.
