We're dividing 21592181 by 489 
We're looking to find how many times 489 goes into 21592181.

Advancing to step 1:
489 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 489

Advancing to step 2:
The number 489 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 489

Let's proceed to step 3:
The number 489 fits into 215 0 times, leaving a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 215 after subtracting 0 from 215.
Fetch the next digit (9) from the dividend, attach it to 215 and continue: 2159 / 489

Advancing to step 4:
The number 489 fits into 2159 4 times, leaving a remainder of 203.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 1956 from 2159 leaves us with 203.
Grab the next digit (2) from the dividend, add it to 203, then carry on: 2032 / 489

Let's proceed to step 5:
The number 489 fits into 2032 4 times, leaving a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we take 1956 away from 2032, we end up with 76.
Take the next digit (1) from the dividend and append it to 76, then repeat: 761 / 489

Going ahead to step 6:
If we divide 761 by 489, we get 1 and a remainder of 272.
Use 1 as the next digit of our solution. 
Result so far: 441.0
If we take 489 away from 761, we end up with 272.
Append the next digit (8) from the dividend to 272 and continue with: 2728 / 489

Advancing to step 7:
When dividing 2728 by 489, we get 5 with a remainder of 283.
Use 5 as the next digit of our solution. 
Result so far: 4415.0
The remainder is 283 after subtracting 2445 from 2728.
Take the next digit (1) from the dividend and append it to 283, then repeat: 2831 / 489

Let's proceed to step 8:
2831 divided by 489 is 5 with a remainder of 386.
Write down 5 as next digit of the result. 
Result so far: 44155.0
Subtracting 2445 from 2831 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 9:
3860 divided by 489 is 7 with a remainder of 437.
The number 7 becomes the next digit in our result. 
Result so far: 44155.7
If we subtract 3423 from 3860, we get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Going ahead to step 10:
When dividing 4370 by 489, we get 8 with a remainder of 458.
Put 8 as the next digit of the answer. 
Result so far: 44155.78
If we subtract 3912 from 4370, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 11:
489 goes into 4580 9 times with a remainder of 179.
Write down 9 as next digit of the result. 
Result so far: 44155.789
Subtract 4401 from 4580 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Let's proceed to step 12:
489 can be fit into 1790 3 times, resulting in a remainder of 323.
The next digit of our result is 3. 
Result so far: 44155.7893
The remainder is 323 after subtracting 1467 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Going ahead to step 13:
When dividing 3230 by 489, we get 6 with a remainder of 296.
Use 6 as the next digit of our solution. 
Result so far: 44155.78936
Deduct 2934 from 3230 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 14:
The number 489 fits into 2960 6 times, leaving a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 44155.789366
If we take 2934 away from 2960, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 44155.789366, with a leftover of 2.6e-06.
