450644 ÷ 6 
We want to figure out the number of times 450644 can be divided by 6.

On to step 1:
6 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 6

Let's proceed to step 2:
6 goes into 45 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 42 away from 45, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 6

Let's proceed to step 3:
The number 6 fits into 30 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Deduct 30 from 30 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 6

Step 4:
6 goes into 6 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 751.0
Deduct 6 from 6 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 6

Going ahead to step 5:
The number 6 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 7510.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 6

Step 6:
When dividing 44 by 6, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 75107.0
The remainder is 2 after subtracting 42 from 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 6 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 75107.3
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.

Let's proceed to step 8:
6 goes into 20 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 75107.33
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 final outcome is 75107.33, with a leftover of 0.002.
