Let's divide 20131 by 1
Our goal is to divide 20131 by 1.

Step 1:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 2 from 2, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

On to step 2:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

On to step 3:
1 divided by 1 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 201.0
The remainder is 0 after subtracting 1 from 1.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Step 4:
3 divided by 1 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 2013.0
Subtract 3 from 3 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Moving on to step 5:
When dividing 1 by 1, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 20131.0
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.

Going ahead to step 6:
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: 20131.0
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:
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: 20131.0
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.

The quotient of the division is 20131.0, and the remainder is 0.0.
