We divide 21440 by 85
Let's see how many times 85 fits into 21440.

Advancing to step 1:
2 divided by 85 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 85

Going ahead to step 2:
The number 85 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 85

Going ahead to step 3:
85 can be fit into 214 2 times, resulting in a remainder of 44.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 170 from 214 leaves us with 44.
Fetch the next digit (4) from the dividend, attach it to 44 and continue: 444 / 85

Advancing to step 4:
The number 85 fits into 444 5 times, leaving a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 425 from 444, we get 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 85

On to step 5:
190 divided by 85 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
Deduct 170 from 190 and we're left 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.

Going ahead to step 6:
85 can be fit into 200 2 times, resulting in a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 252.2
Deduct 170 from 200 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
85 can be fit into 300 3 times, resulting in a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 252.23
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
450 divided by 85 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 252.235
Subtracting 425 from 450 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
250 divided by 85 is 2 with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 252.2352
If we subtract 170 from 250, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
85 goes into 800 9 times with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 252.23529
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
85 goes into 350 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 252.235294
Subtract 340 from 350 to 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.

Going ahead to step 12:
If we divide 100 by 85, we get 1 and a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 252.2352941
Subtract 85 from 100 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.

Let's proceed to step 13:
When dividing 150 by 85, we get 1 with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 252.23529411
If we take 85 away from 150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 252.23529411, and the remainder is 6.5e-08.
