766400 ÷ 6 
Let's see how many times 6 fits into 766400.

Advancing to step 1:
If we divide 7 by 6, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 6 from 7 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 6

Going ahead to step 2:
When dividing 16 by 6, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 12 from 16 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 6

Let's proceed to step 3:
The number 6 fits into 46 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 127.0
If we take 42 away from 46, we end up with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 6

Let's proceed to step 4:
When dividing 44 by 6, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 1277.0
Deduct 42 from 44 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 6

On to step 5:
20 divided by 6 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 12773.0
Deduct 18 from 20 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 6

Moving on to step 6:
6 can be fit into 20 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 127733.0
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
6 can be fit into 20 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 127733.3
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 6, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 127733.33
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 127733.33 and a remainder of 0.002.
