We look at the division of 343893 by 43 
We want to figure out the number of times 343893 can be divided by 43.

On to step 1:
If we divide 3 by 43, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 43

Step 2:
43 can be fit into 34 0 times, resulting in a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 43

Step 3:
If we divide 343 by 43, we get 7 and a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 301 away from 343, we end up with 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 43

Moving on to step 4:
428 divided by 43 is 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 79.0
The remainder is 41 after subtracting 387 from 428.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 43

Let's proceed to step 5:
43 can be fit into 419 9 times, resulting in a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 799.0
The remainder is 32 after subtracting 387 from 419.
Take the next digit (3) from the dividend and append it to 32, then repeat: 323 / 43

Going ahead to step 6:
The number 43 fits into 323 7 times, leaving a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 7997.0
Subtract 301 from 323 to 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.

Advancing to step 7:
43 goes into 220 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 7997.5
If we take 215 away from 220, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
50 divided by 43 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 7997.51
Subtracting 43 from 50 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
When dividing 70 by 43, we get 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 7997.511
The remainder is 27 after subtracting 43 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 7997.511 with a remaining 0.0027.
