6866887 divided by 809 
Our goal is to divide 6866887 by 809.

Moving on to step 1:
When dividing 6 by 809, we get 0 with 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 (8) of the dividend behind the 6 and repeat the process: 68 / 809

Advancing to step 2:
68 divided by 809 is 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Fetch the next digit (6) from the dividend, attach it to 68 and continue: 686 / 809

Moving on to step 3:
809 goes into 686 0 times with a remainder of 686.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 686 and we're left with 686.
Fetch the next digit (6) from the dividend, attach it to 686 and continue: 6866 / 809

Moving on to step 4:
809 goes into 6866 8 times with a remainder of 394.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 6472 from 6866 leaves us with 394.
Append the next digit (8) from the dividend to 394 and continue with: 3948 / 809

Moving on to step 5:
If we divide 3948 by 809, we get 4 and a remainder of 712.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Deduct 3236 from 3948 and we're left with 712.
Take the next digit (8) from the dividend and append it to 712, then repeat: 7128 / 809

Step 6:
7128 divided by 809 is 8 with a remainder of 656.
The number 8 becomes the next digit in our result. 
Result so far: 848.0
The remainder is 656 after subtracting 6472 from 7128.
Take the next digit (7) from the dividend and append it to 656, then repeat: 6567 / 809

Moving on to step 7:
809 goes into 6567 8 times with a remainder of 95.
Record the quotient 8 as the next digit in the result. 
Result so far: 8488.0
Subtract 6472 from 6567 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 8:
If we divide 950 by 809, we get 1 and a remainder of 141.
Use 1 as the next digit of our solution. 
Result so far: 8488.1
The remainder is 141 after subtracting 809 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 9:
809 can be fit into 1410 1 times, resulting in a remainder of 601.
The number 1 becomes the next digit in our result. 
Result so far: 8488.11
Deduct 809 from 1410 and we're left with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Our division results in 8488.11 with a remaining 0.601.
