We look at the division of 313851 by 1 
We're looking to find how many times 1 goes into 313851.

Going ahead to step 1:
When dividing 3 by 1, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 3 from 3, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Moving on to step 2:
If we divide 1 by 1, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 1 away from 1, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Moving on to step 3:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 313.0
If we subtract 3 from 3, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

On to step 4:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 3138.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Let's proceed to step 5:
1 goes into 5 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 31385.0
If we subtract 5 from 5, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Advancing to step 6:
1 divided by 1 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 313851.0
If we subtract 1 from 1, 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.

Let's proceed to step 7:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 313851.0
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.

Moving on to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 313851.0
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.

Our division results in 313851.0 with a remaining 0.0.
