We look at the division of 851247 by 43 
We're looking to find how many times 43 goes into 851247.

On to step 1:
When dividing 8 by 43, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 43

Let's proceed to step 2:
The number 43 fits into 85 1 times, leaving a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 43 from 85 leaves us with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 43

Step 3:
43 can be fit into 421 9 times, resulting in a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 387 from 421, we get 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 43

Advancing to step 4:
The number 43 fits into 342 7 times, leaving a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 197.0
Subtracting 301 from 342 leaves us with 41.
Bring next digit (4) of the dividend behind the 41 and repeat the process: 414 / 43

Step 5:
414 divided by 43 is 9 with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 1979.0
If we subtract 387 from 414, we get 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 43

Step 6:
277 divided by 43 is 6 with a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 19796.0
Subtracting 258 from 277 leaves us 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 7:
If we divide 190 by 43, we get 4 and a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 19796.4
Subtract 172 from 190 to get 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 8:
When dividing 180 by 43, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 19796.44
The remainder is 8 after subtracting 172 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 19796.44 and a remainder of 0.008.
