We're dividing 574184 by 21 
We're looking to find how many times 21 goes into 574184.

Going ahead to step 1:
21 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 21

Going ahead to step 2:
If we divide 57 by 21, we get 2 and a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 42 from 57 leaves us with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 21

Step 3:
The number 21 fits into 154 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 147 away from 154, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 21

Going ahead to step 4:
71 divided by 21 is 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 273.0
Subtracting 63 from 71 leaves us with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 21

Advancing to step 5:
The number 21 fits into 88 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 2734.0
The remainder is 4 after subtracting 84 from 88.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 21

Advancing to step 6:
When dividing 44 by 21, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 27342.0
If we take 42 away from 44, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 27342.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
200 divided by 21 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 27342.09
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
21 goes into 110 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 27342.095
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
21 goes into 50 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 27342.0952
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 27342.09523
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
If we divide 170 by 21, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 27342.095238
Subtract 168 from 170 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
20 divided by 21 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 27342.095238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 27342.09523809
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 27342.09523809 and a remainder of 1.1e-08.
