21408 divided by 22 
We're looking to find how many times 22 goes into 21408.

On to step 1:
2 divided by 22 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 22

Let's proceed to step 2:
The number 22 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 22

Going ahead to step 3:
The number 22 fits into 214 9 times, leaving a remainder of 16.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 198 from 214, we get 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 22

Moving on to step 4:
22 can be fit into 160 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 97.0
Subtracting 154 from 160 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 22

Advancing to step 5:
68 divided by 22 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 973.0
The remainder is 2 after subtracting 66 from 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 6:
20 divided by 22 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 973.0
Subtract 0 from 20 to 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 7:
200 divided by 22 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 973.09
If we subtract 198 from 200, we 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.

On to step 8:
The number 22 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 973.09
Deduct 0 from 20 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.

On to step 9:
22 goes into 200 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 973.0909
Subtract 198 from 200 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.

On to step 10:
22 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 973.0909
Subtract 0 from 20 to 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 11:
22 can be fit into 200 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 973.090909
If we subtract 198 from 200, we 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.

Advancing to step 12:
22 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 973.090909
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.

Advancing to step 13:
22 can be fit into 200 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 973.09090909
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 973.09090909 and a remainder of 2e-09.
