We divide 217249 by 45
We're looking to find how many times 45 goes into 217249.

Going ahead to step 1:
If we divide 2 by 45, we get 0 and 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 45

Moving on to step 2:
The number 45 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 45

Moving on to step 3:
If we divide 217 by 45, we get 4 and a remainder of 37.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 180 from 217, we get 37.
Append the next digit (2) from the dividend to 37 and continue with: 372 / 45

Going ahead to step 4:
The number 45 fits into 372 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 48.0
If we take 360 away from 372, we end up with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 45

Step 5:
When dividing 124 by 45, we get 2 with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 482.0
Deduct 90 from 124 and we're left with 34.
Grab the next digit (9) from the dividend, add it to 34, then carry on: 349 / 45

Advancing to step 6:
The number 45 fits into 349 7 times, leaving a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 4827.0
If we take 315 away from 349, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
340 divided by 45 is 7 with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 4827.7
The remainder is 25 after subtracting 315 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
250 divided by 45 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 4827.75
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
45 goes into 250 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 4827.755
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 4827.755 with a remainder of 0.0025.
