149425 ÷ 1 
We want to divide 149425 by 1.

Step 1:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 1 from 1 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Advancing to step 2:
When dividing 4 by 1, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 4 from 4, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

On to step 3:
9 divided by 1 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
The remainder is 0 after subtracting 9 from 9.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Let's proceed to step 4:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 1494.0
Subtract 4 from 4 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

On to step 5:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 14942.0
Deduct 2 from 2 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Step 6:
When dividing 5 by 1, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 149425.0
The remainder is 0 after subtracting 5 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 149425.0
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.

Moving on to step 8:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 149425.0
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.

The final result is 149425.0 with a remainder of 0.0.
