Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 489

Going ahead to step 2:
When dividing 22 by 489, we get 0 with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 489

Going ahead to step 3:
When dividing 221 by 489, we get 0 with a remainder of 221.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 221 to get 221.
Bring next digit (8) of the dividend behind the 221 and repeat the process: 2218 / 489

Moving on to step 4:
2218 divided by 489 is 4 with a remainder of 262.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 262 after subtracting 1956 from 2218.
Grab the next digit (0) from the dividend, add it to 262, then carry on: 2620 / 489

Going ahead to step 5:
The number 489 fits into 2620 5 times, leaving a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 2445 from 2620 leaves us with 175.
Include the next digit (1) from the dividend after 175, then repeat: 1751 / 489

Step 6:
When dividing 1751 by 489, we get 3 with a remainder of 284.
Write down 3 as next digit of the result. 
Result so far: 453.0
The remainder is 284 after subtracting 1467 from 1751.
Include the next digit (4) from the dividend after 284, then repeat: 2844 / 489

Step 7:
2844 divided by 489 is 5 with a remainder of 399.
The number 5 becomes the next digit in our result. 
Result so far: 4535.0
The remainder is 399 after subtracting 2445 from 2844.
Fetch the next digit (5) from the dividend, attach it to 399 and continue: 3995 / 489

Advancing to step 8:
3995 divided by 489 is 8 with a remainder of 83.
Record the quotient 8 as the next digit in the result. 
Result so far: 45358.0
The remainder is 83 after subtracting 3912 from 3995.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 9:
830 divided by 489 is 1 with a remainder of 341.
Write down 1 as next digit of the result. 
Result so far: 45358.1
Subtracting 489 from 830 leaves us with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 10:
When dividing 3410 by 489, we get 6 with a remainder of 476.
The number 6 becomes the next digit in our result. 
Result so far: 45358.16
Deduct 2934 from 3410 and we're left with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Advancing to step 11:
489 goes into 4760 9 times with a remainder of 359.
Use 9 as the next digit of our solution. 
Result so far: 45358.169
The remainder is 359 after subtracting 4401 from 4760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 12:
When dividing 3590 by 489, we get 7 with a remainder of 167.
Write down 7 as next digit of the result. 
Result so far: 45358.1697
Deduct 3423 from 3590 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 13:
When dividing 1670 by 489, we get 3 with a remainder of 203.
Write down 3 as next digit of the result. 
Result so far: 45358.16973
If we subtract 1467 from 1670, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 14:
If we divide 2030 by 489, we get 4 and a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 45358.169734
If we subtract 1956 from 2030, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 15:
If we divide 740 by 489, we get 1 and a remainder of 251.
Use 1 as the next digit of our solution. 
Result so far: 45358.1697341
If we subtract 489 from 740, we get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Step 16:
The number 489 fits into 2510 5 times, leaving a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 45358.16973415
Deduct 2445 from 2510 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

In conclusion, the division gives 45358.16973415 with a balance of 6.5e-08.
