525115 ÷ 43 
We're looking to find how many times 43 goes into 525115.

Moving on to step 1:
The number 43 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 43

Moving on to step 2:
If we divide 52 by 43, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 43 from 52 leaves us with 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 43

Step 3:
When dividing 95 by 43, we get 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 86 from 95 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 43

Advancing to step 4:
43 goes into 91 2 times with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 122.0
If we subtract 86 from 91, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 43

On to step 5:
When dividing 51 by 43, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1221.0
Subtracting 43 from 51 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 43

Going ahead to step 6:
The number 43 fits into 85 1 times, leaving a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 12211.0
Subtracting 43 from 85 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.

Going ahead to step 7:
43 can be fit into 420 9 times, resulting in a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 12211.9
If we subtract 387 from 420, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 8:
When dividing 330 by 43, we get 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 12211.97
If we take 301 away from 330, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
When dividing 290 by 43, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 12211.976
The remainder is 32 after subtracting 258 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
The number 43 fits into 320 7 times, leaving a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 12211.9767
If we take 301 away from 320, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 11:
If we divide 190 by 43, we get 4 and a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 12211.97674
Subtract 172 from 190 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
The number 43 fits into 180 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 12211.976744
The remainder is 8 after subtracting 172 from 180.
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 12211.976744 with a remaining 8e-07.
