857683 ÷ 43 
We're looking to find how many times 43 goes into 857683.

On to step 1:
43 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 43

Moving on to step 2:
The number 43 fits into 85 1 times, leaving a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 43 away from 85, we end up with 42.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 43

Step 3:
If we divide 427 by 43, we get 9 and a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 387 away from 427, we end up with 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 43

Step 4:
When dividing 406 by 43, we get 9 with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 199.0
Subtracting 387 from 406 leaves us with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 43

Advancing to step 5:
43 can be fit into 198 4 times, resulting in a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 1994.0
Subtract 172 from 198 to get 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 43

Step 6:
If we divide 263 by 43, we get 6 and a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 19946.0
Subtracting 258 from 263 leaves us 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:
50 divided by 43 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 19946.1
The remainder is 7 after subtracting 43 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
43 can be fit into 70 1 times, resulting in a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 19946.11
Subtract 43 from 70 to 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.

The final outcome is 19946.11, with a leftover of 0.027.
