We look at the division of 686036 by 43 
We're looking to find how many times 43 goes into 686036.

Step 1:
The number 43 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 43

Moving on to step 2:
43 goes into 68 1 times with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 25 after subtracting 43 from 68.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 43

Let's proceed to step 3:
43 goes into 256 5 times with a remainder of 41.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 41 after subtracting 215 from 256.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 43

Advancing to step 4:
The number 43 fits into 410 9 times, leaving a remainder of 23.
The next digit of our result is 9. 
Result so far: 159.0
Deduct 387 from 410 and we're left with 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 43

Going ahead to step 5:
233 divided by 43 is 5 with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 1595.0
Subtract 215 from 233 to get 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 43

Going ahead to step 6:
When dividing 186 by 43, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 15954.0
Deduct 172 from 186 and we're left 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.

Let's proceed to step 7:
When dividing 140 by 43, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 15954.3
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.

Advancing to step 8:
110 divided by 43 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 15954.32
If we take 86 away from 110, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
When dividing 240 by 43, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15954.325
If we subtract 215 from 240, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
43 can be fit into 250 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 15954.3255
If we subtract 215 from 250, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 15954.3255, and the remainder is 0.00035.
