We divide 217479 by 45
We're looking to find how many times 45 goes into 217479.

Step 1:
The number 45 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 45

Step 2:
When dividing 21 by 45, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 45

Advancing to step 3:
The number 45 fits into 217 4 times, leaving a remainder of 37.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 180 from 217 to get 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 45

Step 4:
45 goes into 374 8 times with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtracting 360 from 374 leaves us with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 45

Let's proceed to step 5:
45 goes into 147 3 times with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 483.0
If we take 135 away from 147, we end up with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 45

Step 6:
The number 45 fits into 129 2 times, leaving a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 4832.0
The remainder is 39 after subtracting 90 from 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
390 divided by 45 is 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 4832.8
If we subtract 360 from 390, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
If we divide 300 by 45, we get 6 and a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 4832.86
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
If we divide 300 by 45, we get 6 and a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 4832.866
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 4832.866 with a remaining 0.003.
