We look at the division of 61218 by 3 
Let's see how many times 3 fits into 61218.

Step 1:
If we divide 6 by 3, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 6 away from 6, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Step 2:
1 divided by 3 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

Moving on to step 3:
3 goes into 12 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 204.0
The remainder is 0 after subtracting 12 from 12.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

On to step 4:
When dividing 1 by 3, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 2040.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Step 5:
3 goes into 18 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 20406.0
Subtract 18 from 18 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.

Let's proceed to step 6:
When dividing 0 by 3, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20406.0
If we take 0 away from 0, 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:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20406.0
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.

The final outcome is 20406.0, with a leftover of 0.0.
