45216943 divided by 209 
We're looking to find how many times 209 goes into 45216943.

Advancing to step 1:
209 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 209

Advancing to step 2:
When dividing 45 by 209, we get 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Append the next digit (2) from the dividend to 45 and continue with: 452 / 209

Advancing to step 3:
The number 209 fits into 452 2 times, leaving a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 418 away from 452, we end up with 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 209

On to step 4:
If we divide 341 by 209, we get 1 and a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 209 away from 341, we end up with 132.
Bring next digit (6) of the dividend behind the 132 and repeat the process: 1326 / 209

Step 5:
The number 209 fits into 1326 6 times, leaving a remainder of 72.
The next digit of our result is 6. 
Result so far: 216.0
If we subtract 1254 from 1326, we get 72.
Include the next digit (9) from the dividend after 72, then repeat: 729 / 209

Going ahead to step 6:
The number 209 fits into 729 3 times, leaving a remainder of 102.
Put 3 as the next digit of the answer. 
Result so far: 2163.0
Subtracting 627 from 729 leaves us with 102.
Grab the next digit (4) from the dividend, add it to 102, then carry on: 1024 / 209

Step 7:
209 can be fit into 1024 4 times, resulting in a remainder of 188.
Put 4 as the next digit of the answer. 
Result so far: 21634.0
If we take 836 away from 1024, we end up with 188.
Include the next digit (3) from the dividend after 188, then repeat: 1883 / 209

Going ahead to step 8:
If we divide 1883 by 209, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 216349.0
The remainder is 2 after subtracting 1881 from 1883.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 209, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 216349.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
209 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 216349.0
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 216349.0 and a remainder of 0.2.
