We look at the division of 862109 by 77 
Let's see how many times 77 fits into 862109.

Moving on to step 1:
If we divide 8 by 77, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 77

Going ahead to step 2:
When dividing 86 by 77, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 77 away from 86, we end up with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 77

Let's proceed to step 3:
The number 77 fits into 92 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 77 from 92 to get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 77

Step 4:
77 can be fit into 151 1 times, resulting in a remainder of 74.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
Deduct 77 from 151 and we're left with 74.
Take the next digit (0) from the dividend and append it to 74, then repeat: 740 / 77

Advancing to step 5:
The number 77 fits into 740 9 times, leaving a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 1119.0
Subtract 693 from 740 to get 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 77

Advancing to step 6:
When dividing 479 by 77, we get 6 with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 11196.0
If we subtract 462 from 479, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
If we divide 170 by 77, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 11196.2
If we subtract 154 from 170, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
77 goes into 160 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 11196.22
Deduct 154 from 160 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 11196.22 and a remainder of 0.006.
