221561 ÷ 3 
We're looking to find how many times 3 goes into 221561.

On to step 1:
2 divided by 3 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 3

Going ahead to step 2:
When dividing 22 by 3, we get 7 with a remainder of 1.
The next digit of our result is 7. 
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

Advancing to step 3:
If we divide 11 by 3, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 73.0
Subtract 9 from 11 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 3

Step 4:
3 goes into 25 8 times with a remainder of 1.
The next digit of our result is 8. 
Result so far: 738.0
Deduct 24 from 25 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 3

Moving on to step 5:
16 divided by 3 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 7385.0
Subtracting 15 from 16 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 3

On to step 6:
3 can be fit into 11 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 73853.0
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:
20 divided by 3 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 73853.6
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.

Advancing to step 8:
When dividing 20 by 3, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 73853.66
If we take 18 away from 20, we end up 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.

The quotient of the division is 73853.66, and the remainder is 0.002.
