We're dividing 687666 by 84 
We want to figure out the number of times 687666 can be divided by 84.

Going ahead to step 1:
The number 84 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 84

Step 2:
68 divided by 84 is 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Bring next digit (7) of the dividend behind the 68 and repeat the process: 687 / 84

Step 3:
When dividing 687 by 84, we get 8 with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 672 away from 687, we end up with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 84

Going ahead to step 4:
156 divided by 84 is 1 with a remainder of 72.
The next digit of our result is 1. 
Result so far: 81.0
The remainder is 72 after subtracting 84 from 156.
Include the next digit (6) from the dividend after 72, then repeat: 726 / 84

On to step 5:
84 goes into 726 8 times with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 818.0
Deduct 672 from 726 and we're left with 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 84

Step 6:
84 can be fit into 546 6 times, resulting in a remainder of 42.
The next digit of our result is 6. 
Result so far: 8186.0
Deduct 504 from 546 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
If we divide 420 by 84, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8186.5
If we take 420 away from 420, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 84 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8186.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 84 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8186.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 8186.5 and a remainder of 0.0.
