We look at the division of 3131121 by 28 
Let's see how many times 28 fits into 3131121.

Advancing to step 1:
28 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
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 / 28

Moving on to step 2:
When dividing 31 by 28, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 28 away from 31, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 28

Moving on to step 3:
If we divide 33 by 28, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 28 from 33 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 28

On to step 4:
51 divided by 28 is 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 111.0
If we subtract 28 from 51, we get 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 28

Let's proceed to step 5:
28 goes into 231 8 times with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 1118.0
If we subtract 224 from 231, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 28

Moving on to step 6:
If we divide 72 by 28, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 11182.0
Subtracting 56 from 72 leaves us with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 28

Step 7:
28 can be fit into 161 5 times, resulting in a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 111825.0
Subtract 140 from 161 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
28 goes into 210 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 111825.7
Deduct 196 from 210 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
140 divided by 28 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 111825.75
Subtract 140 from 140 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.

Let's proceed to step 10:
28 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 111825.75
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.

Let's proceed to step 11:
28 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 111825.75
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 111825.75 with a remaining 0.0.
