We look at the division of 221331 by 3 
We're looking to find how many times 3 goes into 221331.

Let's proceed to step 1:
2 divided by 3 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

Advancing to step 2:
3 goes into 22 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 21 from 22 to get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 3

On to step 3:
If we divide 11 by 3, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 73.0
The remainder is 2 after subtracting 9 from 11.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 3

Advancing to step 4:
3 goes into 23 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 737.0
The remainder is 2 after subtracting 21 from 23.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Step 5:
When dividing 23 by 3, we get 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 7377.0
The remainder is 2 after subtracting 21 from 23.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

On to step 6:
The number 3 fits into 21 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 73777.0
The remainder is 0 after subtracting 21 from 21.
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 7:
0 divided by 3 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 73777.0
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.

Step 8:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 73777.0
Deduct 0 from 0 and we're left 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.

After the division, we end up with 73777.0 and a remainder of 0.0.
