20222274 ÷ 515 
We want to divide 20222274 by 515.

On to step 1:
If we divide 2 by 515, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 515

Step 2:
515 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 515

Advancing to step 3:
202 divided by 515 is 0 with a remainder of 202.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 202 leaves us with 202.
Append the next digit (2) from the dividend to 202 and continue with: 2022 / 515

On to step 4:
If we divide 2022 by 515, we get 3 and a remainder of 477.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 1545 from 2022 and we're left with 477.
Append the next digit (2) from the dividend to 477 and continue with: 4772 / 515

Moving on to step 5:
If we divide 4772 by 515, we get 9 and a remainder of 137.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 4635 away from 4772, we end up with 137.
Fetch the next digit (2) from the dividend, attach it to 137 and continue: 1372 / 515

On to step 6:
515 can be fit into 1372 2 times, resulting in a remainder of 342.
Use 2 as the next digit of our solution. 
Result so far: 392.0
If we subtract 1030 from 1372, we get 342.
Include the next digit (7) from the dividend after 342, then repeat: 3427 / 515

Moving on to step 7:
515 goes into 3427 6 times with a remainder of 337.
Put 6 as the next digit of the answer. 
Result so far: 3926.0
The remainder is 337 after subtracting 3090 from 3427.
Grab the next digit (4) from the dividend, add it to 337, then carry on: 3374 / 515

Step 8:
3374 divided by 515 is 6 with a remainder of 284.
Put 6 as the next digit of the answer. 
Result so far: 39266.0
Subtract 3090 from 3374 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 9:
515 goes into 2840 5 times with a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 39266.5
Subtract 2575 from 2840 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 10:
The number 515 fits into 2650 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 39266.55
Subtract 2575 from 2650 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

After the division, we end up with 39266.55 and a remainder of 0.075.
