We divide 574680 by 21
We want to divide 574680 by 21.

Step 1:
When dividing 5 by 21, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 21

On to step 2:
If we divide 57 by 21, we get 2 and a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 42 from 57 to get 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 21

On to step 3:
21 can be fit into 154 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
The remainder is 7 after subtracting 147 from 154.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 21

Going ahead to step 4:
21 goes into 76 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 273.0
The remainder is 13 after subtracting 63 from 76.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 21

Advancing to step 5:
The number 21 fits into 138 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 2736.0
The remainder is 12 after subtracting 126 from 138.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 21

Step 6:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 27365.0
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
21 goes into 150 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 27365.7
If we take 147 away from 150, we end up 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.

Let's proceed to step 8:
If we divide 30 by 21, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 27365.71
Subtracting 21 from 30 leaves us 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 9:
21 goes into 90 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 27365.714
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
21 can be fit into 60 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 27365.7142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
180 divided by 21 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 27365.71428
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.

Step 12:
21 can be fit into 120 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 27365.714285
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 27365.7142857
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 27365.71428571
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.

The final outcome is 27365.71428571, with a leftover of 9e-09.
