We're dividing 780434 by 31 
We want to divide 780434 by 31.

Advancing to step 1:
If we divide 7 by 31, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 31

Moving on to step 2:
When dividing 78 by 31, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 62 away from 78, we end up with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 31

Going ahead to step 3:
31 can be fit into 160 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 155 from 160 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 31

Going ahead to step 4:
54 divided by 31 is 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 251.0
Deduct 31 from 54 and we're left with 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 31

Advancing to step 5:
If we divide 233 by 31, we get 7 and a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 2517.0
If we subtract 217 from 233, we get 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 31

Advancing to step 6:
If we divide 164 by 31, we get 5 and a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 25175.0
The remainder is 9 after subtracting 155 from 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
31 can be fit into 90 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 25175.2
Subtracting 62 from 90 leaves us 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.

Let's proceed to step 8:
31 goes into 280 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 25175.29
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
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: 25175.29
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
The number 31 fits into 100 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 25175.2903
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.

Advancing to step 11:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 25175.29032
If we subtract 62 from 70, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 25175.290322
Subtracting 62 from 80 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 25175.290322 with a balance of 1.8e-06.
