We divide 509858 by 84
We want to divide 509858 by 84.

On to step 1:
When dividing 5 by 84, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 84

Step 2:
The number 84 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 84

Moving on to step 3:
84 can be fit into 509 6 times, resulting in a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 504 from 509 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 84

Moving on to step 4:
84 can be fit into 58 0 times, resulting in a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
If we take 0 away from 58, we end up with 58.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 84

Step 5:
If we divide 585 by 84, we get 6 and a remainder of 81.
Put 6 as the next digit of the answer. 
Result so far: 606.0
If we subtract 504 from 585, we get 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 84

On to step 6:
The number 84 fits into 818 9 times, leaving a remainder of 62.
Write down 9 as next digit of the result. 
Result so far: 6069.0
Subtracting 756 from 818 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 7:
84 goes into 620 7 times with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 6069.7
Subtract 588 from 620 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
84 can be fit into 320 3 times, resulting in a remainder of 68.
The next digit of our result is 3. 
Result so far: 6069.73
If we subtract 252 from 320, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
If we divide 680 by 84, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 6069.738
If we take 672 away from 680, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 84 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 6069.738
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
The number 84 fits into 800 9 times, leaving a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 6069.73809
Deduct 756 from 800 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
The number 84 fits into 440 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 6069.738095
Subtract 420 from 440 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
200 divided by 84 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 6069.7380952
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
If we divide 320 by 84, we get 3 and a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 6069.73809523
If we take 252 away from 320, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 6069.73809523, with a leftover of 6.8e-08.
