645454 divided by 10 
We want to divide 645454 by 10.

Let's proceed to step 1:
6 divided by 10 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 10

Advancing to step 2:
When dividing 64 by 10, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 60 from 64 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 10

Moving on to step 3:
45 divided by 10 is 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 64.0
Subtracting 40 from 45 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 10

Step 4:
10 can be fit into 54 5 times, resulting in a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 645.0
If we subtract 50 from 54, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 10

Moving on to step 5:
When dividing 45 by 10, we get 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 6454.0
Deduct 40 from 45 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 10

Advancing to step 6:
The number 10 fits into 54 5 times, leaving a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 64545.0
Subtract 50 from 54 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 10, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 64545.4
If we take 40 away from 40, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
When dividing 0 by 10, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 64545.4
If we subtract 0 from 0, we 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.

Moving on to step 9:
10 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 64545.4
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 64545.4 and a remainder of 0.0.
