52521 divided by 43 
Let's see how many times 43 fits into 52521.

Advancing 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.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 43

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
The remainder is 9 after subtracting 43 from 52.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 43

On to step 3:
If we divide 95 by 43, we get 2 and a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 86 from 95 and we're left with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 43

On to step 4:
43 can be fit into 92 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 122.0
The remainder is 6 after subtracting 86 from 92.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 43

Let's proceed to step 5:
61 divided by 43 is 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1221.0
If we subtract 43 from 61, we 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.

Moving on to step 6:
When dividing 180 by 43, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 1221.4
Subtract 172 from 180 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
When dividing 80 by 43, we get 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1221.41
Subtracting 43 from 80 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 8:
The number 43 fits into 370 8 times, leaving a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 1221.418
Subtracting 344 from 370 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
When dividing 260 by 43, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 1221.4186
The remainder is 2 after subtracting 258 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
20 divided by 43 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1221.4186
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
43 can be fit into 200 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 1221.418604
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
When dividing 280 by 43, we get 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 1221.4186046
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
If we divide 220 by 43, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 1221.41860465
Subtract 215 from 220 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 1221.41860465, with a leftover of 5e-09.
