We're dividing 308451 by 10 
We want to figure out the number of times 308451 can be divided by 10.

Advancing to step 1:
3 divided by 10 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 10

Advancing to step 2:
10 goes into 30 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 30 away from 30, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 10

On to step 3:
8 divided by 10 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 10

Step 4:
84 divided by 10 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 308.0
If we take 80 away from 84, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 10

Step 5:
The number 10 fits into 45 4 times, leaving a remainder of 5.
The next digit of our result is 4. 
Result so far: 3084.0
Subtracting 40 from 45 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 10

Advancing to step 6:
10 goes into 51 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 30845.0
If we subtract 50 from 51, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
If we divide 10 by 10, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 30845.1
If we subtract 10 from 10, 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.

Advancing to step 8:
10 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 30845.1
Subtracting 0 from 0 leaves us 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.

Going ahead to step 9:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30845.1
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 30845.1 with a remainder of 0.0.
