399862 ÷ 43 
We want to divide 399862 by 43.

Moving on to step 1:
The number 43 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 43

Advancing to step 2:
When dividing 39 by 43, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 43

Step 3:
When dividing 399 by 43, we get 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 387 from 399 and we're left with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 43

Moving on to step 4:
43 can be fit into 128 2 times, resulting in a remainder of 42.
The next digit of our result is 2. 
Result so far: 92.0
Subtracting 86 from 128 leaves us with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 43

Moving on to step 5:
The number 43 fits into 426 9 times, leaving a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 929.0
Subtracting 387 from 426 leaves us with 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 43

Advancing to step 6:
If we divide 392 by 43, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 9299.0
If we take 387 away from 392, 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.

Going ahead to step 7:
When dividing 50 by 43, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 9299.1
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.

Advancing to step 8:
If we divide 70 by 43, we get 1 and a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 9299.11
Deduct 43 from 70 and we're left 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.

The quotient of the division is 9299.11, and the remainder is 0.027.
