303432 ÷ 31 
Our goal is to divide 303432 by 31.

Step 1:
If we divide 3 by 31, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 31

Going ahead to step 2:
The number 31 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 31

Going ahead to step 3:
When dividing 303 by 31, we get 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 279 from 303, we get 24.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 31

On to step 4:
The number 31 fits into 244 7 times, leaving a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we subtract 217 from 244, we get 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 31

Moving on to step 5:
The number 31 fits into 273 8 times, leaving a remainder of 25.
The next digit of our result is 8. 
Result so far: 978.0
If we subtract 248 from 273, we get 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 31

Advancing to step 6:
31 goes into 252 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 9788.0
Deduct 248 from 252 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 divided by 31 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 9788.1
If we subtract 31 from 40, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
90 divided by 31 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 9788.12
Deduct 62 from 90 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
280 divided by 31 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 9788.129
If we subtract 279 from 280, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
31 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 9788.129
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
31 goes into 100 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 9788.12903
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
When dividing 70 by 31, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 9788.129032
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
When dividing 80 by 31, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 9788.1290322
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 9788.1290322, and the remainder is 1.8e-07.
