Let's divide 313890 by 1
We want to figure out the number of times 313890 can be divided by 1.

On to step 1:
3 divided by 1 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 3 from 3 and we're left with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Step 2:
1 divided by 1 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 1 from 1 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Going ahead to step 3:
If we divide 3 by 1, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 313.0
Subtracting 3 from 3 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

On to step 4:
When dividing 8 by 1, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 3138.0
Subtracting 8 from 8 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Advancing to step 5:
If we divide 9 by 1, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 31389.0
Subtracting 9 from 9 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Moving on to step 6:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 313890.0
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.

Going ahead to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 313890.0
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.

Moving on to step 8:
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: 313890.0
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.

The final result is 313890.0 with a remainder of 0.0.
