219866 divided by 45 
We want to figure out the number of times 219866 can be divided by 45.

Going ahead to step 1:
2 divided by 45 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 subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 45

Let's proceed to step 2:
21 divided by 45 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 45

On to step 3:
When dividing 219 by 45, we get 4 with a remainder of 39.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 180 from 219, we get 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 45

Let's proceed to step 4:
When dividing 398 by 45, we get 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 48.0
The remainder is 38 after subtracting 360 from 398.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 45

Going ahead to step 5:
If we divide 386 by 45, we get 8 and a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 488.0
Subtracting 360 from 386 leaves us with 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 45

On to step 6:
The number 45 fits into 266 5 times, leaving a remainder of 41.
The next digit of our result is 5. 
Result so far: 4885.0
Subtracting 225 from 266 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
The number 45 fits into 410 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 4885.9
The remainder is 5 after subtracting 405 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
If we divide 50 by 45, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 4885.91
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
45 can be fit into 50 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 4885.911
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 4885.911 with a remainder of 0.0005.
