We look at the division of 6861664 by 816 
Our goal is to divide 6861664 by 816.

Advancing to step 1:
When dividing 6 by 816, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 816

Step 2:
816 can be fit into 68 0 times, resulting in a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 816

On to step 3:
The number 816 fits into 686 0 times, leaving a remainder of 686.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 686 and we're left with 686.
Fetch the next digit (1) from the dividend, attach it to 686 and continue: 6861 / 816

On to step 4:
816 can be fit into 6861 8 times, resulting in a remainder of 333.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6528 away from 6861, we end up with 333.
Include the next digit (6) from the dividend after 333, then repeat: 3336 / 816

Step 5:
816 can be fit into 3336 4 times, resulting in a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
The remainder is 72 after subtracting 3264 from 3336.
Append the next digit (6) from the dividend to 72 and continue with: 726 / 816

Moving on to step 6:
The number 816 fits into 726 0 times, leaving a remainder of 726.
Record the quotient 0 as the next digit in the result. 
Result so far: 840.0
If we take 0 away from 726, we end up with 726.
Grab the next digit (4) from the dividend, add it to 726, then carry on: 7264 / 816

Step 7:
816 can be fit into 7264 8 times, resulting in a remainder of 736.
The number 8 becomes the next digit in our result. 
Result so far: 8408.0
Subtracting 6528 from 7264 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Advancing to step 8:
If we divide 7360 by 816, we get 9 and a remainder of 16.
The next digit of our result is 9. 
Result so far: 8408.9
The remainder is 16 after subtracting 7344 from 7360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
816 goes into 160 0 times with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 8408.9
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
816 goes into 1600 1 times with a remainder of 784.
Record the quotient 1 as the next digit in the result. 
Result so far: 8408.901
If we subtract 816 from 1600, we get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Moving on to step 11:
816 can be fit into 7840 9 times, resulting in a remainder of 496.
The number 9 becomes the next digit in our result. 
Result so far: 8408.9019
If we take 7344 away from 7840, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 12:
The number 816 fits into 4960 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 8408.90196
The remainder is 64 after subtracting 4896 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
816 goes into 640 0 times with a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 8408.90196
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 14:
When dividing 6400 by 816, we get 7 with a remainder of 688.
The number 7 becomes the next digit in our result. 
Result so far: 8408.9019607
Subtracting 5712 from 6400 leaves us with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

On to step 15:
The number 816 fits into 6880 8 times, leaving a remainder of 352.
Record the quotient 8 as the next digit in the result. 
Result so far: 8408.90196078
If we subtract 6528 from 6880, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Our division results in 8408.90196078 with a remaining 3.52e-07.
