We divide 819999 by 43
We want to figure out the number of times 819999 can be divided by 43.

Let's proceed to step 1:
The number 43 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 43

Step 2:
43 can be fit into 81 1 times, resulting in a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 43 from 81 leaves us with 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 43

Going ahead to step 3:
389 divided by 43 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 387 from 389, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 43

Let's proceed to step 4:
When dividing 29 by 43, we get 0 with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 190.0
Subtract 0 from 29 to get 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 43

Let's proceed to step 5:
The number 43 fits into 299 6 times, leaving a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 1906.0
If we take 258 away from 299, we end up with 41.
Grab the next digit (9) from the dividend, add it to 41, then carry on: 419 / 43

Moving on to step 6:
43 goes into 419 9 times with a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 19069.0
The remainder is 32 after subtracting 387 from 419.
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 7:
The number 43 fits into 320 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 19069.7
Subtracting 301 from 320 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.

Step 8:
The number 43 fits into 190 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 19069.74
Subtracting 172 from 190 leaves us 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 9:
The number 43 fits into 180 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 19069.744
Deduct 172 from 180 and we're left 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 result is 19069.744 with a remainder of 0.0008.
