Let's divide 309891 by 43
We want to divide 309891 by 43.

On to step 1:
The number 43 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 43

Let's proceed to step 2:
The number 43 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 43

Advancing to step 3:
43 goes into 309 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 7.0
If we take 301 away from 309, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 43

Let's proceed to step 4:
88 divided by 43 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
If we subtract 86 from 88, we get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 43

Step 5:
The number 43 fits into 29 0 times, leaving a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 720.0
If we take 0 away from 29, we end up with 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 43

Going ahead to step 6:
291 divided by 43 is 6 with a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 7206.0
Subtracting 258 from 291 leaves us with 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 7:
The number 43 fits into 330 7 times, leaving a remainder of 29.
The next digit of our result is 7. 
Result so far: 7206.7
The remainder is 29 after subtracting 301 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 8:
The number 43 fits into 290 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 7206.76
If we subtract 258 from 290, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
If we divide 320 by 43, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 7206.767
The remainder is 19 after subtracting 301 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
43 can be fit into 190 4 times, resulting in a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 7206.7674
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.

On to step 11:
The number 43 fits into 180 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 7206.76744
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.

In conclusion, the division gives 7206.76744 with a balance of 8e-06.
