686778 divided by 84 
We want to figure out the number of times 686778 can be divided by 84.

On to step 1:
When dividing 6 by 84, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 84

Let's proceed to step 2:
68 divided by 84 is 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 84

Moving on to step 3:
If we divide 686 by 84, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 672 from 686 to get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 84

On to step 4:
84 can be fit into 147 1 times, resulting in a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
The remainder is 63 after subtracting 84 from 147.
Fetch the next digit (7) from the dividend, attach it to 63 and continue: 637 / 84

Advancing to step 5:
84 can be fit into 637 7 times, resulting in a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 817.0
Subtracting 588 from 637 leaves us with 49.
Bring next digit (8) of the dividend behind the 49 and repeat the process: 498 / 84

Advancing to step 6:
The number 84 fits into 498 5 times, leaving a remainder of 78.
The next digit of our result is 5. 
Result so far: 8175.0
Deduct 420 from 498 and we're left 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.

Advancing to step 7:
780 divided by 84 is 9 with a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 8175.9
If we take 756 away from 780, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
240 divided by 84 is 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 8175.92
If we subtract 168 from 240, we 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 9:
720 divided by 84 is 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 8175.928
If we subtract 672 from 720, 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.

Step 10:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 8175.9285
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.

Moving on to step 11:
84 can be fit into 600 7 times, resulting in a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 8175.92857
Subtract 588 from 600 to 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.

Step 12:
84 goes into 120 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 8175.928571
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.

Going ahead to step 13:
When dividing 360 by 84, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 8175.9285714
Subtract 336 from 360 to 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.

Moving on to step 14:
When dividing 240 by 84, we get 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 8175.92857142
If we take 168 away from 240, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 8175.92857142, and the remainder is 7.2e-08.
