We look at the division of 308970 by 24 
We want to figure out the number of times 308970 can be divided by 24.

Advancing to step 1:
3 divided by 24 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.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 24

Advancing to step 2:
The number 24 fits into 30 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 24 away from 30, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 24

Going ahead to step 3:
68 divided by 24 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 20 after subtracting 48 from 68.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 24

Advancing to step 4:
209 divided by 24 is 8 with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
If we take 192 away from 209, we end up with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 24

Advancing to step 5:
When dividing 177 by 24, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 1287.0
The remainder is 9 after subtracting 168 from 177.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 24

Step 6:
90 divided by 24 is 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 12873.0
If we take 72 away from 90, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
180 divided by 24 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 12873.7
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
24 goes into 120 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12873.75
Deduct 120 from 120 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.

Advancing to step 9:
24 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: 12873.75
If we take 0 away from 0, 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.

On to step 10:
24 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12873.75
If we take 0 away from 0, 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.

After the division, we end up with 12873.75 and a remainder of 0.0.
