We look at the division of 31751157 by 309 
We want to divide 31751157 by 309.

Advancing to step 1:
The number 309 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 309

Going ahead to step 2:
309 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (7) of the dividend behind the 31 and repeat the process: 317 / 309

Advancing to step 3:
309 goes into 317 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 309 away from 317, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 309

Let's proceed to step 4:
The number 309 fits into 85 0 times, leaving a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 85 leaves us with 85.
Take the next digit (1) from the dividend and append it to 85, then repeat: 851 / 309

Step 5:
When dividing 851 by 309, we get 2 with a remainder of 233.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtracting 618 from 851 leaves us with 233.
Include the next digit (1) from the dividend after 233, then repeat: 2331 / 309

Moving on to step 6:
309 goes into 2331 7 times with a remainder of 168.
Record the quotient 7 as the next digit in the result. 
Result so far: 1027.0
If we take 2163 away from 2331, we end up with 168.
Bring next digit (5) of the dividend behind the 168 and repeat the process: 1685 / 309

Let's proceed to step 7:
1685 divided by 309 is 5 with a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 10275.0
The remainder is 140 after subtracting 1545 from 1685.
Append the next digit (7) from the dividend to 140 and continue with: 1407 / 309

Moving on to step 8:
When dividing 1407 by 309, we get 4 with a remainder of 171.
The number 4 becomes the next digit in our result. 
Result so far: 102754.0
If we take 1236 away from 1407, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 9:
If we divide 1710 by 309, we get 5 and a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 102754.5
Subtract 1545 from 1710 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 10:
309 can be fit into 1650 5 times, resulting in a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 102754.55
If we take 1545 away from 1650, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final result is 102754.55 with a remainder of 0.105.
