210480 ÷ 3 
Our goal is to divide 210480 by 3.

Advancing to step 1:
2 divided by 3 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Step 2:
The number 3 fits into 21 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 0 after subtracting 21 from 21.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Let's proceed to step 3:
0 divided by 3 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 70.0
The remainder is 0 after subtracting 0 from 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 3

On to step 4:
When dividing 4 by 3, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 701.0
Deduct 3 from 4 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 3

On to step 5:
3 can be fit into 18 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 7016.0
If we take 18 away from 18, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 3

On to step 6:
3 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 70160.0
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.

Let's proceed to step 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 70160.0
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.

Step 8:
3 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 70160.0
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.

The final result is 70160.0 with a remainder of 0.0.
