We look at the division of 803913 by 84 
We want to figure out the number of times 803913 can be divided by 84.

Advancing to step 1:
84 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 84

Step 2:
84 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 84

Moving on to step 3:
803 divided by 84 is 9 with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 756 from 803 to get 47.
Bring next digit (9) of the dividend behind the 47 and repeat the process: 479 / 84

Going ahead to step 4:
84 goes into 479 5 times with a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 95.0
If we take 420 away from 479, we end up with 59.
Take the next digit (1) from the dividend and append it to 59, then repeat: 591 / 84

Advancing to step 5:
591 divided by 84 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 957.0
Subtracting 588 from 591 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 84

Step 6:
The number 84 fits into 33 0 times, leaving a remainder of 33.
The next digit of our result is 0. 
Result so far: 9570.0
The remainder is 33 after subtracting 0 from 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
When dividing 330 by 84, we get 3 with a remainder of 78.
Write down 3 as next digit of the result. 
Result so far: 9570.3
If we take 252 away from 330, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 8:
84 can be fit into 780 9 times, resulting in a remainder of 24.
The next digit of our result is 9. 
Result so far: 9570.39
If we subtract 756 from 780, we get 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 9:
84 can be fit into 240 2 times, resulting in a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 9570.392
Subtract 168 from 240 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 10:
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: 9570.3928
If we take 672 away from 720, we end up 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.

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: 9570.39285
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.

Moving on to step 12:
84 can be fit into 600 7 times, resulting in a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 9570.392857
If we take 588 away from 600, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
When dividing 120 by 84, we get 1 with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 9570.3928571
Deduct 84 from 120 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.

On to step 14:
84 can be fit into 360 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 9570.39285714
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.

After the division, we end up with 9570.39285714 and a remainder of 2.4e-08.
