589944 divided by 21 
Let's see how many times 21 fits into 589944.

Going ahead to step 1:
5 divided by 21 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 21

Let's proceed to step 2:
21 goes into 58 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 42 from 58 leaves us with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 21

Advancing to step 3:
21 goes into 169 8 times with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 168 away from 169, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 21

Advancing to step 4:
21 goes into 19 0 times with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 280.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 21

Advancing to step 5:
If we divide 194 by 21, we get 9 and a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 2809.0
Subtracting 189 from 194 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 21

Step 6:
54 divided by 21 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 28092.0
Deduct 42 from 54 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
The number 21 fits into 120 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 28092.5
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 28092.57
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
The number 21 fits into 30 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 28092.571
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
If we divide 90 by 21, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 28092.5714
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 28092.57142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 28092.571428
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
If we divide 120 by 21, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 28092.5714285
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
21 goes into 150 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 28092.57142857
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 28092.57142857 with a balance of 3e-09.
