Let's divide 648108 by 84
We're looking to find how many times 84 goes into 648108.

Going ahead to step 1:
If we divide 6 by 84, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 84

Moving on to step 2:
The number 84 fits into 64 0 times, leaving a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 84

Moving on to step 3:
648 divided by 84 is 7 with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 588 from 648 and we're left with 60.
Include the next digit (1) from the dividend after 60, then repeat: 601 / 84

Moving on to step 4:
84 can be fit into 601 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
If we take 588 away from 601, we end up with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 84

Step 5:
130 divided by 84 is 1 with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 771.0
The remainder is 46 after subtracting 84 from 130.
Grab the next digit (8) from the dividend, add it to 46, then carry on: 468 / 84

On to step 6:
If we divide 468 by 84, we get 5 and a remainder of 48.
Record the quotient 5 as the next digit in the result. 
Result so far: 7715.0
If we subtract 420 from 468, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
84 can be fit into 480 5 times, resulting in a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 7715.5
Deduct 420 from 480 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
If we divide 600 by 84, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 7715.57
If we subtract 588 from 600, we get 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 9:
If we divide 120 by 84, we get 1 and a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 7715.571
Subtract 84 from 120 to 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.

Advancing to step 10:
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: 7715.5714
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.

Going ahead to step 11:
The number 84 fits into 240 2 times, leaving a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 7715.57142
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.

Going ahead to step 12:
720 divided by 84 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 7715.571428
Subtracting 672 from 720 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 13:
When dividing 480 by 84, we get 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 7715.5714285
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.

Step 14:
The number 84 fits into 600 7 times, leaving a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 7715.57142857
Subtracting 588 from 600 leaves us 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.

After the division, we end up with 7715.57142857 and a remainder of 1.2e-08.
