131331 ÷ 51 
Let's see how many times 51 fits into 131331.

Step 1:
1 divided by 51 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 51

Let's proceed to step 2:
If we divide 13 by 51, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 51

Let's proceed to step 3:
131 divided by 51 is 2 with a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 102 from 131 leaves us with 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 51

On to step 4:
51 goes into 293 5 times with a remainder of 38.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 255 from 293, we get 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 51

Advancing to step 5:
The number 51 fits into 383 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 257.0
If we take 357 away from 383, we end up with 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 51

Let's proceed to step 6:
If we divide 261 by 51, we get 5 and a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 2575.0
Deduct 255 from 261 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
If we divide 60 by 51, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 2575.1
Subtracting 51 from 60 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
The number 51 fits into 90 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 2575.11
Subtract 51 from 90 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 2575.11 and a remainder of 0.039.
