We look at the division of 859311 by 43 
We're looking to find how many times 43 goes into 859311.

Advancing to step 1:
The number 43 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 43

Going ahead to step 2:
43 can be fit into 85 1 times, resulting in a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 42 after subtracting 43 from 85.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 43

On to step 3:
43 can be fit into 429 9 times, resulting in a remainder of 42.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 387 from 429 to get 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 43

Going ahead to step 4:
If we divide 423 by 43, we get 9 and a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
Deduct 387 from 423 and we're left with 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 43

On to step 5:
The number 43 fits into 361 8 times, leaving a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 1998.0
Subtract 344 from 361 to get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 43

Let's proceed to step 6:
The number 43 fits into 171 3 times, leaving a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 19983.0
Subtracting 129 from 171 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
If we divide 420 by 43, we get 9 and a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 19983.9
The remainder is 33 after subtracting 387 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 8:
If we divide 330 by 43, we get 7 and a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 19983.97
The remainder is 29 after subtracting 301 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
The number 43 fits into 290 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 19983.976
Deduct 258 from 290 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
When dividing 320 by 43, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 19983.9767
If we take 301 away from 320, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
43 can be fit into 190 4 times, resulting in a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 19983.97674
Deduct 172 from 190 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
43 goes into 180 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 19983.976744
Subtracting 172 from 180 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 19983.976744, with a leftover of 8e-07.
