645992 ÷ 6 
We're looking to find how many times 6 goes into 645992.

Let's proceed to step 1:
If we divide 6 by 6, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 0 after subtracting 6 from 6.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 6

Let's proceed to step 2:
When dividing 4 by 6, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 6

On to step 3:
When dividing 45 by 6, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 107.0
If we take 42 away from 45, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 6

Step 4:
39 divided by 6 is 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 1076.0
The remainder is 3 after subtracting 36 from 39.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 6

Moving on to step 5:
If we divide 39 by 6, we get 6 and a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 10766.0
The remainder is 3 after subtracting 36 from 39.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 6

Let's proceed to step 6:
6 can be fit into 32 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 107665.0
Subtract 30 from 32 to get 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 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: 107665.3
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.

Advancing to step 8:
20 divided by 6 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 107665.33
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 107665.33, and the remainder is 0.002.
