We're dividing 510409 by 22 
Let's see how many times 22 fits into 510409.

Step 1:
If we divide 5 by 22, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 22

Step 2:
The number 22 fits into 51 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 44 from 51 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 22

On to step 3:
If we divide 70 by 22, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 66 from 70 to get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 22

Going ahead to step 4:
22 goes into 44 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 232.0
The remainder is 0 after subtracting 44 from 44.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 22

Step 5:
22 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2320.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 22

On to step 6:
22 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 23200.0
Deduct 0 from 9 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 22 fits into 90 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 23200.4
Subtracting 88 from 90 leaves us 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.

Let's proceed 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: 23200.4
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 9:
The number 22 fits into 200 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 23200.409
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.

Let's proceed to step 10:
The number 22 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 23200.409
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.

Going ahead to step 11:
22 can be fit into 200 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 23200.40909
If we take 198 away from 200, 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.

Let's proceed to step 12:
When dividing 20 by 22, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 23200.40909
Subtracting 0 from 20 leaves us 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 13:
22 goes into 200 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 23200.4090909
Subtracting 198 from 200 leaves us 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 14:
22 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 23200.4090909
If we take 0 away from 20, 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.

The final result is 23200.4090909 with a remainder of 2e-08.
