We look at the division of 78993152 by 84 
Let's see how many times 84 fits into 78993152.

Let's proceed to step 1:
84 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 84

Let's proceed to step 2:
When dividing 78 by 84, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 84

On to step 3:
When dividing 789 by 84, we get 9 with a remainder of 33.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 756 from 789, we get 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 84

Going ahead to step 4:
When dividing 339 by 84, we get 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 94.0
The remainder is 3 after subtracting 336 from 339.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 84

On to step 5:
33 divided by 84 is 0 with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 940.0
The remainder is 33 after subtracting 0 from 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 84

Moving on to step 6:
The number 84 fits into 331 3 times, leaving a remainder of 79.
The next digit of our result is 3. 
Result so far: 9403.0
Subtract 252 from 331 to get 79.
Include the next digit (5) from the dividend after 79, then repeat: 795 / 84

On to step 7:
795 divided by 84 is 9 with a remainder of 39.
The next digit of our result is 9. 
Result so far: 94039.0
Subtract 756 from 795 to get 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 84

Going ahead to step 8:
The number 84 fits into 392 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 940394.0
If we take 336 away from 392, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
When dividing 560 by 84, we get 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 940394.6
Subtract 504 from 560 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
If we divide 560 by 84, we get 6 and a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 940394.66
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 940394.66, and the remainder is 0.056.
