818857 ÷ 43 
We want to divide 818857 by 43.

Step 1:
When dividing 8 by 43, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 43

Going ahead to step 2:
43 goes into 81 1 times with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 43 from 81, we get 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 43

Moving on to step 3:
43 can be fit into 388 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 387 from 388 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 43

Step 4:
The number 43 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 190.0
Subtract 0 from 18 to get 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 43

Step 5:
When dividing 185 by 43, we get 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 1904.0
Subtracting 172 from 185 leaves us with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 43

Advancing to step 6:
When dividing 137 by 43, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 19043.0
If we take 129 away from 137, we end up 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.

Going ahead to step 7:
If we divide 80 by 43, we get 1 and a remainder of 37.
The next digit of our result is 1. 
Result so far: 19043.1
Deduct 43 from 80 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 8:
370 divided by 43 is 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 19043.18
Subtracting 344 from 370 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
When dividing 260 by 43, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 19043.186
Subtracting 258 from 260 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
20 divided by 43 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 19043.186
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
200 divided by 43 is 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 19043.18604
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
If we divide 280 by 43, we get 6 and a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 19043.186046
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
When dividing 220 by 43, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 19043.1860465
If we take 215 away from 220, we end up 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.

Moving on to step 14:
43 goes into 50 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 19043.18604651
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.

After the division, we end up with 19043.18604651 and a remainder of 7e-09.
