We look at the division of 43929 by 84 
We're looking to find how many times 84 goes into 43929.

Moving on to step 1:
If we divide 4 by 84, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 84

Going ahead to step 2:
If we divide 43 by 84, we get 0 and a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Grab the next digit (9) from the dividend, add it to 43, then carry on: 439 / 84

Let's proceed to step 3:
If we divide 439 by 84, we get 5 and a remainder of 19.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 420 from 439 and we're left with 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 84

On to step 4:
The number 84 fits into 192 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 52.0
Subtract 168 from 192 to get 24.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 84

On to step 5:
249 divided by 84 is 2 with a remainder of 81.
The number 2 becomes the next digit in our result. 
Result so far: 522.0
Subtracting 168 from 249 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 6:
When dividing 810 by 84, we get 9 with a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 522.9
Deduct 756 from 810 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
540 divided by 84 is 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 522.96
Deduct 504 from 540 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
When dividing 360 by 84, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 522.964
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
84 can be fit into 240 2 times, resulting in a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 522.9642
If we take 168 away from 240, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
When dividing 720 by 84, we get 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 522.96428
The remainder is 48 after subtracting 672 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 522.964285
If we subtract 420 from 480, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
When dividing 600 by 84, we get 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 522.9642857
If we subtract 588 from 600, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
If we divide 120 by 84, we get 1 and a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 522.96428571
Subtract 84 from 120 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.

The final outcome is 522.96428571, with a leftover of 3.6e-08.
