42811212 ÷ 209 
We want to divide 42811212 by 209.

Advancing to step 1:
209 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 209

Advancing to step 2:
209 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 209

Advancing to step 3:
209 goes into 428 2 times with a remainder of 10.
The next digit of our result is 2. 
Result so far: 2.0
If we take 418 away from 428, we end up with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 209

Moving on to step 4:
When dividing 101 by 209, we get 0 with a remainder of 101.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 101 to get 101.
Include the next digit (1) from the dividend after 101, then repeat: 1011 / 209

Step 5:
209 goes into 1011 4 times with a remainder of 175.
Use 4 as the next digit of our solution. 
Result so far: 204.0
If we subtract 836 from 1011, we get 175.
Include the next digit (2) from the dividend after 175, then repeat: 1752 / 209

Advancing to step 6:
The number 209 fits into 1752 8 times, leaving a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 2048.0
If we subtract 1672 from 1752, we get 80.
Bring next digit (1) of the dividend behind the 80 and repeat the process: 801 / 209

Moving on to step 7:
801 divided by 209 is 3 with a remainder of 174.
Use 3 as the next digit of our solution. 
Result so far: 20483.0
Subtract 627 from 801 to get 174.
Include the next digit (2) from the dividend after 174, then repeat: 1742 / 209

Step 8:
When dividing 1742 by 209, we get 8 with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 204838.0
If we subtract 1672 from 1742, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
209 can be fit into 700 3 times, resulting in a remainder of 73.
The next digit of our result is 3. 
Result so far: 204838.3
Subtracting 627 from 700 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 10:
The number 209 fits into 730 3 times, leaving a remainder of 103.
Put 3 as the next digit of the answer. 
Result so far: 204838.33
If we subtract 627 from 730, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

After the division, we end up with 204838.33 and a remainder of 0.103.
