We divide 439900 by 43
Let's see how many times 43 fits into 439900.

Moving on to step 1:
When dividing 4 by 43, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 43

Step 2:
When dividing 43 by 43, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 43 from 43 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 43

Step 3:
The number 43 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 43

Moving on to step 4:
43 goes into 99 2 times with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 102.0
If we take 86 away from 99, we end up with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 43

Moving on to step 5:
When dividing 130 by 43, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 1023.0
Subtracting 129 from 130 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 43

On to step 6:
If we divide 10 by 43, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10230.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
43 can be fit into 100 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 10230.2
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
140 divided by 43 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 10230.23
If we subtract 129 from 140, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
43 goes into 110 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 10230.232
Subtracting 86 from 110 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
43 goes into 240 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 10230.2325
Subtract 215 from 240 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
43 goes into 250 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 10230.23255
If we take 215 away from 250, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 10230.23255 with a remainder of 3.5e-05.
