We're dividing 450377 by 10 
We want to figure out the number of times 450377 can be divided by 10.

On to step 1:
10 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 10

Going ahead to step 2:
When dividing 45 by 10, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 40 away from 45, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 10

Going ahead to step 3:
The number 10 fits into 50 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we subtract 50 from 50, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 10

Step 4:
The number 10 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 450.0
If we take 0 away from 3, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 10

On to step 5:
If we divide 37 by 10, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 4503.0
Deduct 30 from 37 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 10

On to step 6:
10 can be fit into 77 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 45037.0
Deduct 70 from 77 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
70 divided by 10 is 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 45037.7
Subtract 70 from 70 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 10, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 45037.7
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45037.7
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 45037.7 with a remainder of 0.0.
