We divide 150412 by 1
We want to figure out the number of times 150412 can be divided by 1.

Advancing to step 1:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 1 from 1 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Advancing to step 2:
5 divided by 1 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 5 from 5, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Going ahead to step 3:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Moving on to step 4:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 1504.0
Subtract 4 from 4 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

On to step 5:
1 divided by 1 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 15041.0
The remainder is 0 after subtracting 1 from 1.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Going ahead to step 6:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 150412.0
Deduct 2 from 2 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.

On to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 150412.0
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.

Going ahead to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 150412.0
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.

After the division, we end up with 150412.0 and a remainder of 0.0.
