145090 ÷ 1 
We're looking to find how many times 1 goes into 145090.

Let's proceed to step 1:
The number 1 fits into 1 1 times, leaving 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 1 from 1.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

On to step 2:
If we divide 4 by 1, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 0 after subtracting 4 from 4.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

On to step 3:
1 goes into 5 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
Subtract 5 from 5 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Let's proceed to step 4:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1450.0
Deduct 0 from 0 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Moving on to step 5:
If we divide 9 by 1, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 14509.0
Deduct 9 from 9 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

On to step 6:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 145090.0
The remainder is 0 after subtracting 0 from 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 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 145090.0
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.

Let's proceed to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 145090.0
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 145090.0 with a remainder of 0.0.
