412780 ÷ 31 
We want to figure out the number of times 412780 can be divided by 31.

Moving on to step 1:
4 divided by 31 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 31

Step 2:
31 can be fit into 41 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 31 from 41, we get 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 31

Let's proceed to step 3:
102 divided by 31 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 93 from 102, we get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 31

Step 4:
31 can be fit into 97 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 133.0
If we subtract 93 from 97, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 31

On to step 5:
If we divide 48 by 31, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1331.0
Subtract 31 from 48 to get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 31

Step 6:
When dividing 170 by 31, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 13315.0
The remainder is 15 after subtracting 155 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
31 can be fit into 150 4 times, resulting in a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 13315.4
Deduct 124 from 150 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
If we divide 260 by 31, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 13315.48
Subtracting 248 from 260 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
The number 31 fits into 120 3 times, leaving a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 13315.483
Subtracting 93 from 120 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
31 goes into 270 8 times with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 13315.4838
The remainder is 22 after subtracting 248 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
When dividing 220 by 31, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 13315.48387
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
When dividing 30 by 31, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 13315.48387
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
300 divided by 31 is 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 13315.4838709
Subtract 279 from 300 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 14:
If we divide 210 by 31, we get 6 and a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 13315.48387096
If we take 186 away from 210, we end up 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 outcome is 13315.48387096, with a leftover of 2.4e-08.
