687231 divided by 43 
We want to divide 687231 by 43.

Step 1:
6 divided by 43 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 43

Moving on to step 2:
68 divided by 43 is 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 43 from 68 and we're left with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 43

Going ahead to step 3:
43 goes into 257 5 times with a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 215 away from 257, we end up with 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 43

Advancing to step 4:
43 goes into 422 9 times with a remainder of 35.
The next digit of our result is 9. 
Result so far: 159.0
If we subtract 387 from 422, we get 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 43

Step 5:
353 divided by 43 is 8 with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 1598.0
If we subtract 344 from 353, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 43

Advancing to step 6:
43 can be fit into 91 2 times, resulting in a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 15982.0
Deduct 86 from 91 and we're left 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.

Going ahead to step 7:
43 goes into 50 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 15982.1
If we take 43 away from 50, we end up 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 8:
43 can be fit into 70 1 times, resulting in a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 15982.11
If we subtract 43 from 70, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 15982.11 and a remainder of 0.027.
