We look at the division of 312825 by 1 
We're looking to find how many times 1 goes into 312825.

On to step 1:
1 goes into 3 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 3 from 3 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Moving on to step 2:
The number 1 fits into 1 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 31.0
If we subtract 1 from 1, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Moving on to step 3:
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: 312.0
Deduct 2 from 2 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Advancing to step 4:
If we divide 8 by 1, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 3128.0
The remainder is 0 after subtracting 8 from 8.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Let's proceed to step 5:
2 divided by 1 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 31282.0
The remainder is 0 after subtracting 2 from 2.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Let's proceed to step 6:
5 divided by 1 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 312825.0
If we take 5 away from 5, 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.

Moving on to step 7:
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: 312825.0
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.

Let's proceed to step 8:
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: 312825.0
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.

Our division results in 312825.0 with a remaining 0.0.
