648315 ÷ 84 
Our goal is to divide 648315 by 84.

Advancing to step 1:
If we divide 6 by 84, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 84

Advancing to step 2:
64 divided by 84 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 84

Step 3:
84 can be fit into 648 7 times, resulting in a remainder of 60.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 60 after subtracting 588 from 648.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 84

Going ahead to step 4:
603 divided by 84 is 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtract 588 from 603 to get 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 84

Going ahead to step 5:
The number 84 fits into 151 1 times, leaving a remainder of 67.
The next digit of our result is 1. 
Result so far: 771.0
Subtracting 84 from 151 leaves us with 67.
Bring next digit (5) of the dividend behind the 67 and repeat the process: 675 / 84

Let's proceed to step 6:
The number 84 fits into 675 8 times, leaving a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 7718.0
If we take 672 away from 675, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 84, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 7718.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
When dividing 300 by 84, we get 3 with a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 7718.03
Subtracting 252 from 300 leaves us 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 9:
480 divided by 84 is 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 7718.035
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.

Advancing to step 10:
If we divide 600 by 84, we get 7 and a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 7718.0357
Deduct 588 from 600 and we're left 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.

Moving on to step 11:
120 divided by 84 is 1 with a remainder of 36.
The next digit of our result is 1. 
Result so far: 7718.03571
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.

Let's proceed to step 12:
The number 84 fits into 360 4 times, leaving a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 7718.035714
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.

Step 13:
84 can be fit into 240 2 times, resulting in a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 7718.0357142
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.

Let's proceed to step 14:
If we divide 720 by 84, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 7718.03571428
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.

The final result is 7718.03571428 with a remainder of 4.8e-08.
