We're dividing 639384 by 43 
We're looking to find how many times 43 goes into 639384.

Let's proceed to step 1:
43 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 43

On to step 2:
If we divide 63 by 43, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
If we take 43 away from 63, we end up with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 43

Moving on to step 3:
When dividing 209 by 43, we get 4 with a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 172 from 209 leaves us with 37.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 43

Going ahead to step 4:
43 goes into 373 8 times with a remainder of 29.
Use 8 as the next digit of our solution. 
Result so far: 148.0
Deduct 344 from 373 and we're left with 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 43

Moving on to step 5:
43 goes into 298 6 times with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 1486.0
If we subtract 258 from 298, we get 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 43

Step 6:
404 divided by 43 is 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 14869.0
Deduct 387 from 404 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
The number 43 fits into 170 3 times, leaving a remainder of 41.
The next digit of our result is 3. 
Result so far: 14869.3
Subtract 129 from 170 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 8:
If we divide 410 by 43, we get 9 and a remainder of 23.
The next digit of our result is 9. 
Result so far: 14869.39
If we subtract 387 from 410, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
43 can be fit into 230 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 14869.395
If we take 215 away from 230, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
The number 43 fits into 150 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 14869.3953
Subtract 129 from 150 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
210 divided by 43 is 4 with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 14869.39534
Subtract 172 from 210 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
If we divide 380 by 43, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 14869.395348
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
When dividing 360 by 43, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 14869.3953488
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 14869.3953488 and a remainder of 1.6e-07.
