We're dividing 21710 by 28 
We're looking to find how many times 28 goes into 21710.

Let's proceed to step 1:
The number 28 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 28

Moving on to step 2:
21 divided by 28 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 28

Step 3:
If we divide 217 by 28, we get 7 and a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 196 from 217 leaves us with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 28

Let's proceed to step 4:
28 can be fit into 211 7 times, resulting in a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
If we subtract 196 from 211, we get 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 28

Step 5:
28 can be fit into 150 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 775.0
If we subtract 140 from 150, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 6:
If we divide 100 by 28, we get 3 and a remainder of 16.
The next digit of our result is 3. 
Result so far: 775.3
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
If we divide 160 by 28, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 775.35
If we take 140 away from 160, we end up with 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:
If we divide 200 by 28, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 775.357
If we subtract 196 from 200, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 775.3571
Subtracting 28 from 40 leaves us 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 10:
120 divided by 28 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 775.35714
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
If we divide 80 by 28, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 775.357142
If we take 56 away from 80, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
28 goes into 240 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 775.3571428
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
160 divided by 28 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 775.35714285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 775.35714285, with a leftover of 2e-08.
