399877 divided by 43 
Let's see how many times 43 fits into 399877.

Going ahead to step 1:
43 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 43

Step 2:
When dividing 39 by 43, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 43

On to step 3:
43 can be fit into 399 9 times, resulting in a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 387 from 399 leaves us with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 43

Let's proceed to step 4:
128 divided by 43 is 2 with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Subtract 86 from 128 to get 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 43

Moving on to step 5:
If we divide 427 by 43, we get 9 and a remainder of 40.
The next digit of our result is 9. 
Result so far: 929.0
Subtracting 387 from 427 leaves us with 40.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 43

Step 6:
If we divide 407 by 43, we get 9 and a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 9299.0
Deduct 387 from 407 and we're left 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.

On to step 7:
If we divide 200 by 43, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 9299.4
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
When dividing 280 by 43, we get 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 9299.46
Deduct 258 from 280 and we're left 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.

Let's proceed to step 9:
43 can be fit into 220 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 9299.465
If we subtract 215 from 220, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
50 divided by 43 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 9299.4651
If we take 43 away from 50, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
70 divided by 43 is 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 9299.46511
Subtracting 43 from 70 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 9299.46511 and a remainder of 2.7e-05.
