31121812 ÷ 130 
We want to divide 31121812 by 130.

Moving on to step 1:
3 divided by 130 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 130

Going ahead to step 2:
The number 130 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 130

Let's proceed to step 3:
130 goes into 311 2 times with a remainder of 51.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 260 from 311 leaves us with 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 130

Going ahead to step 4:
130 goes into 512 3 times with a remainder of 122.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 122 after subtracting 390 from 512.
Bring next digit (1) of the dividend behind the 122 and repeat the process: 1221 / 130

Moving on to step 5:
130 goes into 1221 9 times with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 239.0
Subtracting 1170 from 1221 leaves us with 51.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 130

Moving on to step 6:
When dividing 518 by 130, we get 3 with a remainder of 128.
Record the quotient 3 as the next digit in the result. 
Result so far: 2393.0
The remainder is 128 after subtracting 390 from 518.
Fetch the next digit (1) from the dividend, attach it to 128 and continue: 1281 / 130

Going ahead to step 7:
The number 130 fits into 1281 9 times, leaving a remainder of 111.
The number 9 becomes the next digit in our result. 
Result so far: 23939.0
If we take 1170 away from 1281, we end up with 111.
Take the next digit (2) from the dividend and append it to 111, then repeat: 1112 / 130

Advancing to step 8:
1112 divided by 130 is 8 with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 239398.0
The remainder is 72 after subtracting 1040 from 1112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
720 divided by 130 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 239398.5
The remainder is 70 after subtracting 650 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
130 goes into 700 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 239398.55
Deduct 650 from 700 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 239398.55 with a remaining 0.05.
