We're dividing 56429 by 21 
Let's see how many times 21 fits into 56429.

Step 1:
21 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 21

Moving on to step 2:
If we divide 56 by 21, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 42 from 56 and we're left with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 21

Going ahead to step 3:
If we divide 144 by 21, we get 6 and a remainder of 18.
The next digit of our result is 6. 
Result so far: 26.0
If we subtract 126 from 144, we get 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 21

On to step 4:
21 can be fit into 182 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 268.0
If we subtract 168 from 182, we get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 21

Going ahead to step 5:
149 divided by 21 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 2687.0
If we take 147 away from 149, 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.

Moving on to step 6:
21 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 2687.0
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.

Moving on to step 7:
200 divided by 21 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 2687.09
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 2687.095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
50 divided by 21 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2687.0952
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 10:
If we divide 80 by 21, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 2687.09523
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.

Step 11:
When dividing 170 by 21, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 2687.095238
If we take 168 away from 170, 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.

Step 12:
If we divide 20 by 21, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2687.095238
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.

Going ahead to step 13:
21 goes into 200 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 2687.09523809
If we take 189 away from 200, we end up 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.

The quotient of the division is 2687.09523809, and the remainder is 1.1e-08.
