We're dividing 150549 by 10 
We're looking to find how many times 10 goes into 150549.

Step 1:
1 divided by 10 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 10

Moving on to step 2:
When dividing 15 by 10, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 10 from 15 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 10

Let's proceed to step 3:
When dividing 50 by 10, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 50 from 50, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 10

Moving on to step 4:
5 divided by 10 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 150.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 10

Let's proceed to step 5:
When dividing 54 by 10, we get 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 1505.0
Subtracting 50 from 54 leaves us with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 10

Let's proceed to step 6:
When dividing 49 by 10, we get 4 with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 15054.0
The remainder is 9 after subtracting 40 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 10, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 15054.9
Subtracting 90 from 90 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 8:
10 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15054.9
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.

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: 15054.9
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.

The final outcome is 15054.9, with a leftover of 0.0.
