We're dividing 939909 by 43 
We want to figure out the number of times 939909 can be divided by 43.

Going ahead to step 1:
The number 43 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 43

Advancing to step 2:
43 can be fit into 93 2 times, resulting in a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 86 from 93, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 43

Advancing to step 3:
When dividing 79 by 43, we get 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 43 from 79 and we're left with 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 43

Going ahead to step 4:
When dividing 369 by 43, we get 8 with a remainder of 25.
The next digit of our result is 8. 
Result so far: 218.0
Subtracting 344 from 369 leaves us with 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 43

Step 5:
43 can be fit into 250 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 2185.0
Subtracting 215 from 250 leaves us with 35.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 43

Going ahead to step 6:
359 divided by 43 is 8 with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 21858.0
If we subtract 344 from 359, we get 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 7:
43 can be fit into 150 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 21858.3
Deduct 129 from 150 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
210 divided by 43 is 4 with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 21858.34
The remainder is 38 after subtracting 172 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
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: 21858.348
If we subtract 344 from 380, we 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 10:
If we divide 360 by 43, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 21858.3488
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 21858.3488 with a balance of 0.00016.
