130823 divided by 21 
We want to figure out the number of times 130823 can be divided by 21.

Moving on to step 1:
21 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 21

Step 2:
When dividing 13 by 21, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 21

Advancing to step 3:
21 goes into 130 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 4 after subtracting 126 from 130.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 21

Advancing to step 4:
When dividing 48 by 21, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Deduct 42 from 48 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 21

On to step 5:
21 goes into 62 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 622.0
If we subtract 42 from 62, we get 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 21

Advancing to step 6:
If we divide 203 by 21, we get 9 and a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 6229.0
Deduct 189 from 203 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
140 divided by 21 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 6229.6
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
21 goes into 140 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 6229.66
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 6229.66 with a remainder of 0.014.
