We're dividing 520107 by 45 
We're looking to find how many times 45 goes into 520107.

Going ahead to step 1:
5 divided by 45 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 45

Advancing to step 2:
45 goes into 52 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 45 from 52 to get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 45

Advancing to step 3:
When dividing 70 by 45, we get 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 45 from 70 leaves us with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 45

Let's proceed to step 4:
When dividing 251 by 45, we get 5 with a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 115.0
If we take 225 away from 251, we end up with 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 45

Moving on to step 5:
45 goes into 260 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 1155.0
If we subtract 225 from 260, we get 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 45

Let's proceed to step 6:
357 divided by 45 is 7 with a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 11557.0
Subtracting 315 from 357 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
45 goes into 420 9 times with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 11557.9
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.

Step 8:
45 goes into 150 3 times with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 11557.93
If we subtract 135 from 150, we 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.

On to step 9:
150 divided by 45 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 11557.933
Subtracting 135 from 150 leaves us with 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 11557.933 and a remainder of 0.0015.
