153380 ÷ 15 
We want to divide 153380 by 15.

Step 1:
15 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 15

Going ahead to step 2:
When dividing 15 by 15, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 15 from 15.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 15

Let's proceed to step 3:
15 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 15

On to step 4:
15 can be fit into 33 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
If we take 30 away from 33, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 15

On to step 5:
15 goes into 38 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 1022.0
Deduct 30 from 38 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 15

Moving on to step 6:
80 divided by 15 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 10225.0
If we subtract 75 from 80, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 10225.3
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 10225.33
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 10225.33 with a remaining 0.005.
