12131 ÷ 28 
We want to figure out the number of times 12131 can be divided by 28.

Moving on to step 1:
1 divided by 28 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 28

Moving on to step 2:
28 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 28

On to step 3:
If we divide 121 by 28, we get 4 and a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 112 from 121 to get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 28

Moving on to step 4:
28 can be fit into 93 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 43.0
The remainder is 9 after subtracting 84 from 93.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 28

Moving on to step 5:
91 divided by 28 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 433.0
Deduct 84 from 91 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 6:
28 goes into 70 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 433.2
The remainder is 14 after subtracting 56 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
28 can be fit into 140 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 433.25
Subtracting 140 from 140 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.

Let's proceed to step 8:
If we divide 0 by 28, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 433.25
Deduct 0 from 0 and we're left 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 9:
28 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 433.25
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 433.25, and the remainder is 0.0.
