We're dividing 31450 by 20 
Let's see how many times 20 fits into 31450.

Advancing to step 1:
When dividing 3 by 20, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 20

Moving on to step 2:
20 can be fit into 31 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 20 away from 31, we end up with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 20

Let's proceed to step 3:
114 divided by 20 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 100 from 114 to get 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 20

Advancing to step 4:
The number 20 fits into 145 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
If we take 140 away from 145, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 20

Moving on to step 5:
20 goes into 50 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 1572.0
The remainder is 10 after subtracting 40 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 6:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1572.5
Subtracting 100 from 100 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 7:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1572.5
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.

Let's proceed to step 8:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1572.5
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.

The final outcome is 1572.5, with a leftover of 0.0.
