353400 ÷ 31 
We're looking to find how many times 31 goes into 353400.

Let's proceed to step 1:
3 divided by 31 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 31

Step 2:
The number 31 fits into 35 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 4 after subtracting 31 from 35.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 31

Going ahead to step 3:
31 goes into 43 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 31 from 43, we get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 31

Step 4:
31 goes into 124 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Subtract 124 from 124 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 31

Moving on to step 5:
31 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1140.0
The remainder is 0 after subtracting 0 from 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 31

On to step 6:
If we divide 0 by 31, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11400.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
If we divide 0 by 31, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11400.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 31 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11400.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 11400.0, and the remainder is 0.0.
