We're dividing 309135 by 43 
Let's see how many times 43 fits into 309135.

Step 1:
When dividing 3 by 43, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 43

Let's proceed to step 2:
If we divide 30 by 43, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 43

On to step 3:
When dividing 309 by 43, we get 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 301 from 309, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 43

Moving on to step 4:
When dividing 81 by 43, we get 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 71.0
Subtracting 43 from 81 leaves us with 38.
Bring next digit (3) of the dividend behind the 38 and repeat the process: 383 / 43

Let's proceed to step 5:
If we divide 383 by 43, we get 8 and a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 718.0
Deduct 344 from 383 and we're left with 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 43

Advancing to step 6:
43 can be fit into 395 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 7189.0
The remainder is 8 after subtracting 387 from 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
43 goes into 80 1 times with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 7189.1
Subtract 43 from 80 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 8:
43 can be fit into 370 8 times, resulting in a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 7189.18
The remainder is 26 after subtracting 344 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
The number 43 fits into 260 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 7189.186
If we subtract 258 from 260, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
If we divide 20 by 43, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 7189.186
Deduct 0 from 20 and we're left 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.

Step 11:
When dividing 200 by 43, we get 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 7189.18604
If we subtract 172 from 200, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
If we divide 280 by 43, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 7189.186046
The remainder is 22 after subtracting 258 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
The number 43 fits into 220 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7189.1860465
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.

Advancing to step 14:
43 goes into 50 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 7189.18604651
Subtract 43 from 50 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 7189.18604651, and the remainder is 7e-09.
