435519 ÷ 31 
Let's see how many times 31 fits into 435519.

Step 1:
When dividing 4 by 31, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 31

Moving on to step 2:
If we divide 43 by 31, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 31 from 43, we get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 31

Going ahead to step 3:
When dividing 125 by 31, we get 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 124 away from 125, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 31

Let's proceed to step 4:
When dividing 15 by 31, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Subtract 0 from 15 to get 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 31

On to step 5:
When dividing 151 by 31, we get 4 with a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 1404.0
If we take 124 away from 151, we end up with 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 31

Let's proceed to step 6:
31 goes into 279 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 14049.0
Subtract 279 from 279 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
If we divide 0 by 31, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14049.0
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.

Moving on to step 8:
The number 31 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 14049.0
Subtract 0 from 0 to get 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 final result is 14049.0 with a remainder of 0.0.
