We look at the division of 252515 by 43 
We want to figure out the number of times 252515 can be divided by 43.

On to step 1:
The number 43 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 43

Let's proceed to step 2:
When dividing 25 by 43, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 43

Advancing to step 3:
When dividing 252 by 43, we get 5 with a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 37 after subtracting 215 from 252.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 43

Step 4:
If we divide 375 by 43, we get 8 and a remainder of 31.
The next digit of our result is 8. 
Result so far: 58.0
Subtracting 344 from 375 leaves us with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 43

Going ahead to step 5:
If we divide 311 by 43, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 587.0
Subtract 301 from 311 to get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 43

Advancing to step 6:
105 divided by 43 is 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 5872.0
If we subtract 86 from 105, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
The number 43 fits into 190 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 5872.4
Deduct 172 from 190 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
43 goes into 180 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 5872.44
Subtracting 172 from 180 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 5872.44 with a remaining 0.008.
