Let's divide 311161 by 20
We want to divide 311161 by 20.

Moving on to step 1:
3 divided by 20 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 20

Let's proceed to step 2:
If we divide 31 by 20, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 20 from 31, we get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 20

Advancing to step 3:
When dividing 111 by 20, we get 5 with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 100 from 111, we get 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 20

Going ahead to step 4:
20 can be fit into 111 5 times, resulting in a remainder of 11.
The next digit of our result is 5. 
Result so far: 155.0
The remainder is 11 after subtracting 100 from 111.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 20

Let's proceed to step 5:
If we divide 116 by 20, we get 5 and a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 1555.0
The remainder is 16 after subtracting 100 from 116.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 20

On to step 6:
161 divided by 20 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 15558.0
Subtract 160 from 161 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 20 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 15558.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15558.05
If we subtract 100 from 100, 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.

Step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15558.05
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 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15558.05
Subtract 0 from 0 to 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.

Our division results in 15558.05 with a remaining 0.0.
