We're dividing 789863 by 43 
We want to divide 789863 by 43.

Advancing to step 1:
7 divided by 43 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 43

Advancing to step 2:
The number 43 fits into 78 1 times, leaving a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 43 from 78 and we're left with 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 43

Going ahead to step 3:
If we divide 359 by 43, we get 8 and a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 344 away from 359, we end up with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 43

Let's proceed to step 4:
43 goes into 158 3 times with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 183.0
If we subtract 129 from 158, we get 29.
Bring next digit (6) of the dividend behind the 29 and repeat the process: 296 / 43

On to step 5:
When dividing 296 by 43, we get 6 with a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 1836.0
Subtracting 258 from 296 leaves us with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 43

Moving on to step 6:
383 divided by 43 is 8 with a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 18368.0
Deduct 344 from 383 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
43 goes into 390 9 times with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 18368.9
If we take 387 away from 390, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
The number 43 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 18368.9
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
If we divide 300 by 43, we get 6 and a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 18368.906
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
420 divided by 43 is 9 with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 18368.9069
If we take 387 away from 420, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 11:
When dividing 330 by 43, we get 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 18368.90697
If we subtract 301 from 330, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 12:
When dividing 290 by 43, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 18368.906976
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.

Going ahead to step 13:
43 goes into 320 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 18368.9069767
Subtract 301 from 320 to get 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 14:
190 divided by 43 is 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 18368.90697674
If we take 172 away from 190, we end up 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.

The final outcome is 18368.90697674, with a leftover of 1.8e-08.
