686715 divided by 43 
We want to figure out the number of times 686715 can be divided by 43.

On to 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
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 43

Step 2:
The number 43 fits into 68 1 times, leaving a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 43 from 68, we get 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 43

Advancing to step 3:
256 divided by 43 is 5 with a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 215 from 256 and we're left with 41.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 43

Step 4:
When dividing 417 by 43, we get 9 with a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
If we subtract 387 from 417, we get 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 43

Advancing to step 5:
When dividing 301 by 43, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 1597.0
Subtracting 301 from 301 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 43

On to step 6:
5 divided by 43 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 15970.0
Subtract 0 from 5 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.

Let's proceed to step 7:
If we divide 50 by 43, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 15970.1
Deduct 43 from 50 and we're left 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.

Going ahead to step 8:
70 divided by 43 is 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 15970.11
If we take 43 away from 70, we end up with 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 15970.11 and a remainder of 0.027.
