Let's divide 639472 by 43
We're looking to find how many times 43 goes into 639472.

Let's proceed to step 1:
The number 43 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 43

Moving on to step 2:
43 goes into 63 1 times with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 43 from 63 to get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 43

Step 3:
43 can be fit into 209 4 times, resulting in a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 37 after subtracting 172 from 209.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 43

Let's proceed to step 4:
374 divided by 43 is 8 with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
The remainder is 30 after subtracting 344 from 374.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 43

Step 5:
If we divide 307 by 43, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 1487.0
Subtract 301 from 307 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 43

Moving on to step 6:
If we divide 62 by 43, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 14871.0
If we subtract 43 from 62, we 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.

Step 7:
If we divide 190 by 43, we get 4 and a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 14871.4
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.

Moving on to step 8:
The number 43 fits into 180 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 14871.44
The remainder is 8 after subtracting 172 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 14871.44, with a leftover of 0.008.
