786843 ÷ 84 
Let's see how many times 84 fits into 786843.

On to step 1:
If we divide 7 by 84, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 84

Moving on to step 2:
When dividing 78 by 84, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 84

On to step 3:
786 divided by 84 is 9 with a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 756 from 786, we get 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 84

On to step 4:
84 goes into 308 3 times with a remainder of 56.
The next digit of our result is 3. 
Result so far: 93.0
If we take 252 away from 308, we end up with 56.
Bring next digit (4) of the dividend behind the 56 and repeat the process: 564 / 84

Moving on to step 5:
When dividing 564 by 84, we get 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 936.0
If we take 504 away from 564, we end up with 60.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 84

Step 6:
84 can be fit into 603 7 times, resulting in a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 9367.0
If we subtract 588 from 603, 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.

Moving on to step 7:
150 divided by 84 is 1 with a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 9367.1
If we take 84 away from 150, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 8:
If we divide 660 by 84, we get 7 and a remainder of 72.
The number 7 becomes the next digit in our result. 
Result so far: 9367.17
Deduct 588 from 660 and we're left 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.

Let's proceed to step 9:
84 can be fit into 720 8 times, resulting in a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 9367.178
Deduct 672 from 720 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
84 goes into 480 5 times with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 9367.1785
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.

On to step 11:
84 can be fit into 600 7 times, resulting in a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 9367.17857
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
The number 84 fits into 120 1 times, leaving a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 9367.178571
If we subtract 84 from 120, 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 13:
360 divided by 84 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 9367.1785714
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
84 can be fit into 240 2 times, resulting in a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 9367.17857142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 9367.17857142, with a leftover of 7.2e-08.
