Let's divide 515220 by 45
We want to divide 515220 by 45.

Let's proceed to step 1:
If we divide 5 by 45, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 45

On to step 2:
When dividing 51 by 45, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 45 away from 51, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 45

Step 3:
45 can be fit into 65 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 45 from 65 to get 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 45

Moving on to step 4:
45 can be fit into 202 4 times, resulting in a remainder of 22.
The next digit of our result is 4. 
Result so far: 114.0
If we subtract 180 from 202, we get 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 45

Going ahead to step 5:
45 can be fit into 222 4 times, resulting in a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 1144.0
Subtracting 180 from 222 leaves us with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 45

Going ahead to step 6:
If we divide 420 by 45, we get 9 and a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 11449.0
The remainder is 15 after subtracting 405 from 420.
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 7:
The number 45 fits into 150 3 times, leaving a remainder of 15.
The next digit of our result is 3. 
Result so far: 11449.3
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
When dividing 150 by 45, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 11449.33
Subtract 135 from 150 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.

After the division, we end up with 11449.33 and a remainder of 0.015.
