140409 divided by 43 
Our goal is to divide 140409 by 43.

Going ahead to step 1:
1 divided by 43 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 43

Let's proceed to step 2:
14 divided by 43 is 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 43

Step 3:
140 divided by 43 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 129 from 140, we get 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 43

Advancing to step 4:
The number 43 fits into 114 2 times, leaving a remainder of 28.
The next digit of our result is 2. 
Result so far: 32.0
Subtract 86 from 114 to get 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 43

Advancing to step 5:
280 divided by 43 is 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 326.0
If we take 258 away from 280, we end up with 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 43

Advancing to step 6:
229 divided by 43 is 5 with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 3265.0
Subtracting 215 from 229 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
When dividing 140 by 43, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3265.3
Subtract 129 from 140 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
110 divided by 43 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 3265.32
The remainder is 24 after subtracting 86 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
43 can be fit into 240 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3265.325
Deduct 215 from 240 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
250 divided by 43 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 3265.3255
Deduct 215 from 250 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 3265.3255 with a remaining 0.00035.
