We divide 300221 by 3
Our goal is to divide 300221 by 3.

On to step 1:
3 goes into 3 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 3 from 3 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 3

Step 2:
0 divided by 3 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 0, we end up with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Going ahead to step 3:
If we divide 0 by 3, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 3

Let's proceed to step 4:
The number 3 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 1000.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 3

Advancing to step 5:
When dividing 22 by 3, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 10007.0
Deduct 21 from 22 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 3

Advancing to step 6:
3 can be fit into 11 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 100073.0
The remainder is 2 after subtracting 9 from 11.
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 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 100073.6
Subtracting 18 from 20 leaves us 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.

Let's proceed to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 100073.66
Subtract 18 from 20 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.

The final outcome is 100073.66, with a leftover of 0.002.
