400306 ÷ 43 
We want to figure out the number of times 400306 can be divided by 43.

Going ahead to step 1:
When dividing 4 by 43, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 43

Let's proceed to step 2:
43 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 43

Step 3:
43 can be fit into 400 9 times, resulting in a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 387 from 400 to get 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 43

Going ahead to step 4:
If we divide 133 by 43, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 93.0
Subtract 129 from 133 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 43

Going ahead to step 5:
43 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 930.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 43

Step 6:
43 goes into 406 9 times with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 9309.0
If we take 387 away from 406, we end up 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.

On to step 7:
43 can be fit into 190 4 times, resulting in a remainder of 18.
The next digit of our result is 4. 
Result so far: 9309.4
Deduct 172 from 190 and we're left 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.

Moving on to step 8:
43 goes into 180 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 9309.44
Subtracting 172 from 180 leaves us 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 quotient of the division is 9309.44, and the remainder is 0.008.
