We look at the division of 31220361 by 302 
We want to divide 31220361 by 302.

Let's proceed to step 1:
302 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 302

Step 2:
When dividing 31 by 302, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 302

Moving on to step 3:
The number 302 fits into 312 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 302 from 312 leaves us with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 302

Going ahead to step 4:
The number 302 fits into 102 0 times, leaving a remainder of 102.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 102 after subtracting 0 from 102.
Include the next digit (0) from the dividend after 102, then repeat: 1020 / 302

Advancing to step 5:
302 can be fit into 1020 3 times, resulting in a remainder of 114.
The next digit of our result is 3. 
Result so far: 103.0
Subtracting 906 from 1020 leaves us with 114.
Include the next digit (3) from the dividend after 114, then repeat: 1143 / 302

Advancing to step 6:
302 can be fit into 1143 3 times, resulting in a remainder of 237.
Record the quotient 3 as the next digit in the result. 
Result so far: 1033.0
If we subtract 906 from 1143, we get 237.
Take the next digit (6) from the dividend and append it to 237, then repeat: 2376 / 302

Let's proceed to step 7:
302 can be fit into 2376 7 times, resulting in a remainder of 262.
Record the quotient 7 as the next digit in the result. 
Result so far: 10337.0
If we take 2114 away from 2376, we end up with 262.
Fetch the next digit (1) from the dividend, attach it to 262 and continue: 2621 / 302

Moving on to step 8:
The number 302 fits into 2621 8 times, leaving a remainder of 205.
Record the quotient 8 as the next digit in the result. 
Result so far: 103378.0
If we subtract 2416 from 2621, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 9:
302 goes into 2050 6 times with a remainder of 238.
Put 6 as the next digit of the answer. 
Result so far: 103378.6
If we subtract 1812 from 2050, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 10:
When dividing 2380 by 302, we get 7 with a remainder of 266.
Record the quotient 7 as the next digit in the result. 
Result so far: 103378.67
If we take 2114 away from 2380, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 11:
When dividing 2660 by 302, we get 8 with a remainder of 244.
Write down 8 as next digit of the result. 
Result so far: 103378.678
If we subtract 2416 from 2660, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 12:
2440 divided by 302 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 103378.6788
Subtracting 2416 from 2440 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 103378.6788 with a remainder of 0.00024.
